Prayer (Salah) is one of the five pillars of Islam and holds great significance. It is a unique type of worship, which is also seen as a Muslim identity across the world. It comprises multiple acts and postures. Ruku (Bowing) is one of these special postures, which reflects submission and humility before Allah سُبْحَانَهُۥ وَتَعَالَىٰ, while Glorifying Him.
There are multiple positions and places in the performance of Prayer, where Muslims are enjoined to make specific duas. Ruku is one of the postures, alongside Sujood (Prostration), which are directly emphasized in the Quran in several verses, such as the 77th verse of Surah Al-Hajj.
Translation - O you who believe, bow in adoration, worship your Lord and do what is good that you may find success.
Accordingly, reciting Dua during Ruku is also a highly virtuous and Sunnah act. What to say in Ruku or more precisely, what to recite in Ruku in Salah, is specifically advised by the Prophet Muhammad صَلَّى ٱللَّٰهُ عَلَيْهِۦ وَسَلَّمَ, as communicated through different Hadiths, reported in authentic Hadith Collections. Bowing or bending into the position of Ruku is a gesture of Glorifying Allah, سُبْحَانَهُۥ وَتَعَالَىٰ, while saying Dua in Rukoo is a focal point in Prayer, where the believers affirm their unconditional and unwavering submission to their Creator. It is an act of humbleness and denying one’s ego, while acknowledging the absolute supremacy of Allah سُبْحَانَهُۥ وَتَعَالَىٰ. That’s why supplication during ruku is believed to be one of the special moments when the probability of acceptance of Dua is the highest.
The most virtuous and widely practiced dua for ruku in Salah, recited by the Prophet Muhammad صَلَّى ٱللَّٰهُ عَلَيْهِۦ وَسَلَّمَ, is reported in many Hadiths, such as Hadith 1046 of Sunan An-Nasai.
Translation - It was narrated that Hudhaifah said: "I prayed with the Messenger of Allah (ﷺ), and he bowed and said when bowing: 'Subhana Rabbial-azim (Glory be to my Lord Almighty).' And when prostrating: 'Subhana Rabbial-'Ala (Glory be to my Lord Most High).”
The same Dua is also reported in Hadith 1133 and 1145 of Sunan An-Nasai, with more details. Additionally, there is another Dua to recite while in Ruku, which is also narrated in Hadith 1122 of Sunan An-Nasai, as follows:
Translation - It was narrated that 'Aishah said: "The Messenger of Allah (ﷺ) used to say when bowing and prostrating: 'Subhanakallahumma, Rabbana wa bihamdik. Allahumma-ghfirli (Glory be to You O Allah, Our Lord, and praise. O Allah, forgive me," following the command of the Quran.
The same dua is also reported in Hadith 1123 of Sunan An-Nasai. Similarly, another Dua, which the Prophet used to recite in Ruku, is also reported in Hadith 487a of Sahih Muslim:
Translation - A'isha reported that the Messenger of Allah (may peace be upon him) used to pronounce while bowing and prostrating himself: All Glorious, All Holy, Lord of the Angels and the Spirit.
Prayer Duas
Subhaana Rabbiyal-'Adheem.
Glory to my Lord the Exalted. (Three times)
Subhaanaka Allaahumma Rabbanaa wa bihamdika Allaahum-maghfir lee.
Glory is to You, O Allah, our Lord, and praise is Yours. O Allah, forgive me.
Subboohun, Quddoosun, Rabbul-malaa'ikati warrooh.
Glory (to You), Most Holy (are You), Lord of the angels and the Spirit.
Allaahumma laka raka'tu, wa bika 'aamantu, wa laka 'aslamtu khasha'a laka sam'ee, wa basaree, wa mukhkhee, wa 'adhmee, wa 'asabee, wa mastaqalla bihi qadamee.
O Allah, to You I bow (in prayer) and in You I believe and to You I have submitted. Before You my hearing is humbled, as is my sight, my mind, my bones, my nerves and what my feet have mounted upon (for travel).
Although there are multiple Duas, which can be recited while in ruku, as reported in different Hadiths, the most widely practiced dua, across the Muslim world, is as follows
Arabic Text - سُبْحَانَ رَبِّيَ الْعَظِيمِ
This dua should be recited three times, while staying in the posture of Ruku.
Transliteration - Subhaana Rabbiyal-'Adheem.
English Text - Glory to my Lord the Exalted
Dua - سُبْحَانَ رَبِّيَ الْعَظِيمِ
Meaning – By dictionary, this dua translates to “Glory to my Allah سُبْحَانَهُۥ وَتَعَالَىٰ, the Exalted”. While staying in the position of Ruku, reciting this Dua thrice reflects the total submission of the believers before the Almighty Allah سُبْحَانَهُۥ وَتَعَالَىٰ. It is a reflection of humility in front of Allah سُبْحَانَهُۥ وَتَعَالَىٰ and affirming His Glory. When we say these words while bending in Ruku, it is the denial of our ego and complete submission before the Glorious and Exalted Allah سُبْحَانَهُۥ وَتَعَالَىٰ. Repeating it three times, consecutively, is a sort of reaffirmation of our submission.
Prayer is when the believer stands before his creator, knowing the Almighty is listening to him. At such a moment, making a dua that voices the glory of Allah (سُبْحَانَهُ وَتَعَالَى) is an extremely potent way of attaining forgiveness of one's sins from Him in addition to multitudes of blessings and sustenance of Allah. Thus, while making this dua, one must fully concentrate and should wholeheartedly recite the dua.
The etiquette of reciting Dua while in Ruku includes the following:
IMORTANT
Reciting the dua while in rukoo is a ticket to forgiveness from the Almighty. If you recite this dua, Allah Azzawajal will increase your good deeds and shower blessings upon you. Most notably, He will accept your salah as salah is incomplete without reciting this dua in rukoo. The dua reminds us of our place in the world, the sovereignty of Allah (سُبْحَانَهُ وَتَعَالَى), and our ultimate dependence on Him for every small thing in life.
The significance and spiritual benefits of reciting Dua in Ruku can be summarized as follows:
While bowing in Ruku in Prayer, it is mandatory to recite any of the authentic duas mentioned in authentic Hadiths. The most popular dua, practiced across the Muslim world, is "سُبْحَانَ رَبِّيَ الْعَظِيم”, which has to be recited three times in one ruku.
Yes, some scholars are of the opinion that making personal dua is allowed, while in ruku in Salah. However, the majority consensus and highly emphasized practice is to recite one of the Duas, which are mentioned in authentic Hadiths. Moreover, if you want to make a personal Dua while in Ruku, it must be in Arabic.
The majority consensus on this issue is that dua during Ruku must be made in Arabic, especially during the obligatory prayers. While dua can be made in any language on other occasions, while praying, only the authentic Duas, as reported in Hadiths, must be recited in Arabic.
The recommended practice is to ensure memorizing the permissible Dua for recitation while in Ruku. However, if you forget while in Ruku, your prayer remains valid, but you must maintain the posture of Ruku for a reasonable time.
