Abu Umamah Sudaiy bin 'Ajlan Al-Bahili (May Allah be pleased with him) reported:
The Prophet (ﷺ) said: "Nothing is dearer to Allah than two drops and two marks: A drop of tears shed out of fear of Allah and a drop of blood shed in Allah's way. Regarding the two marks, they are: Marks left in the Cause of Allah and a mark left in observing one of the obligatory act of worship of Allah, the Exalted".[At-Tirmidhi].
