A Selected Hadith
Narrated 'Ubada bin As-Samit:
We gave the oath of allegiance to Allah's Apostle that we would listen to and obey him both at the time when we were active and at the time when we were tired and that we would not fight...
O Allah, I seek refuge in You from the punishment of the grave, and from the punishment of Hell-fire, and from the trials of life and death, and from the evil of the trial of the False Messiah.
