'Abdullah bin Shikh-kheer Radiyallahu 'Anhu says:
"I attended the noble assembly of Rasulullah Sallallahu 'Alayhi Wasallam. He was performing salaah. Because of his crying, such sound emmitted from his chest, like that of a boiling pot".
'Abdullah bin Mas'ud Radiyallahu 'Anhu says:
"Rasulullah Sallallahu 'Alayhi Wasallam once asked me to recite the Qur-aan to him. (He might have said this because one might be able to concentrate more when one is listens, or he may have said this for another reason, which may include many reasons. For example, the hearing of the recital of the Qur-aan is regarded as a sunnah, as a result of this deed of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam) I said: ''O Messenger of Allah, should I recite it to you when it has been revealed to you?' (Sayyidina ibn Mas'ud Radiyallahu 'Anhu may have thought this recital was for tabligh as a reminder) Rasulullah Sallallahu 'Alayhi Wasallam said: 'I love to hear it from another person'' Thereupon I began reciting Surah Nisaa (which begins from the last quarter of the 4th juz). When I reached this aayah: ''But how (will it be with them) when We bring of every people a witness, and We bring thee (O Muhammed) a witness against these?''-Surah Nisaa,41 I saw tears flowing from both eyes of Rasulullah Sallallahu 'Alayhi Wasallam.
'Abdullah bin 'Umar Radiyallahu 'Anhu reports:
"In the time of Rasulullah Sallallahu 'Alayhi Wasallam there once occurred a solar eclipse (According to the majority of the 'ulama this incident took place in the tenth year hijri). Rasulullah Sallallahu 'Alayhi Wasallam went into the masjid, commenced salaah, and stood in qiyaam for so long that it was felt that he did not intend to perform the ruku'. (In another narration it is stated that he recited the Surah Baqarah.) He then performed such a long ruku as if he did not want to come up from the Ruku'. Then in the same manner after standing up from the ruku' he stood up for such a long time as if he did not want to perform sajdah, here too he kept his mubaarak head on the ground for such a long time as if he was not going to lift his mubaarak head. In this manner he did the same after lifting the head and sitting in jalsa, and after the jalsa in the second sajdah.In short, in every rukn of the salaah this was done, that every rukn was so long, as if this rukn was going to be performed till the end, and there is nothing after it. (In the same manner he performed the second rak'ah, and in the last sajdah), due to the intense fear he began taking heavy breaths and crying, and began pleading to the Almighty Allah that 'O Allah, it is only You that have promised that when these people make istighfaar there will be no punishment'. This saying of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam refers to the aayah that is at the end of the ninth juz: ''But Allah would not punish them while thou was with them, nor will He punish them while they seek forgiveness. - Surah Al-Anfaal, 33.When Rasulullah Sallallahu 'Alayhi Wasallam completed the salaah, the sun had cleared already. Rasulullah Sallahu 'Alayhi Wasallam delivered a sermon after this. After uttering the hamd and thanaa, he talked o this subject, that the sun and moon does not eclipse because of the death or birth of anyone, but both are from among the signs of Allah Ta'aala. (That gives His creation a warning so that they may fear Him). When the eclipses occurs then immediately turn towards Allah (begin istighfaar and performing salaah)"
Ibn 'Abbaas Radiyallahu 'Anhu reports that one of the daughters of Rasulullah Sallallahu 'Alayhi Wasallam was on her death bed. Rasulullah Sallallahu 'Alayhi Wasallam picked her up and put her before him. She passed away in his presence. Ummi Ayman (who was a slave girl of Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam) began wailing aloud. Rasulullah Sallallahu 'Alayhi Wasallam said:
"Are you crying before the Messenger of Allah?" (because tears were also flowing from the eyes of Sayyidina Rasulullah Sallallahu'Alayhi Wasallam). She said: 'Do I not see you cry?' Rasulullah Sallallahu 'Alayhi Wasallam replied: "This crying is not prohibited. It is a mercy of Allah". (He softens the hearts of His servants, and creates love and mercy in them). Rasulullah Sallallahu'Alayhi Wasallam then said: "A Muslim is at peace at all times. even when his soul is being taken out, he is busy uttering the hamd (praises) of Allah".
'Aayeshah Radiyallahu 'Anha reports:
"Rasulullah Sallallahu 'Alayhi Wasallam kissed the forehead of 'Uthmaan bin Maz'oon after his death. At that time tears were flowing from his eyes".
Anas Radiyallahu 'Anhu reports:
"Rasulullah Sallallahu 'Alayhi Wasallam was sitting at the grave of his daughter (Sayyiditina Ummi Kulthum Radiyallahu 'Anha) and tears were flowing from his eyes. Sayyidina Rasulullah Sallallahu 'Alayhi Wasallam said: 'That person should enter the grave who did not have sexual relations that (previous) night'. Abu Talhah Radiyallahu 'Anhu replied: 'I did not'. At the request of Rasulullah Sallallahu 'Alayhi Wasallam he entered her grave"
