Sunan At-Tirmidhi

Narrated Abu Umamah: That the Prophet (ﷺ) said: ""There is nothing more beloved to Allah than two drops and two traces: A teardrop shed out of fear of Allah, and a drop of blood shed in Allah's cause. As for the two traces: A trace resulting in Allah's cause, and and a trace resulting from one of the duties that Allah made obligatory."" [Abu 'Eisa said:] This Hadith is Hasan Gharib
