Silsilat al-Ahadith al-Sahihah

Abu Nazrah says: A companion became ill, and his companions went to him to look after him. He began to weep. He was asked: O servant of Allah! Why are you weeping? Did the Messenger of Allah (peace and blessings be upon him) not say to you: "Trim your mustache and then remain steadfast upon this until you meet me"? He said: Why not, (indeed, the Prophet peace and blessings be upon him gave me this glad tiding), but I also heard him say: Verily, Allah, the Blessed and Exalted, took a handful (of His servants) with His right hand and said: These are for Paradise, and I do not care about anyone. Then He took another handful with the other hand and said: These are for Hell, and I do not care about anyone." (The reason for my weeping is this concern that) I do not know in which handful I will be.
