Al-Lu'lu Wal-Marjan 533 — The Book of Funerals (Al-Janâ'iz)

Anas bin Malik Narrated from:

The Prophet ﷺ passed by a woman who was weeping beside a grave. He told her to fear Allâh ﷻ and be patient. She said to him, "Go away, for you have not been afflicted with a calamity like mine." And she did not recognise him. Then she was informed that he was the Prophet ﷺ. So she went to the house of the Prophet ﷺ and there she did not find any guard. Then she said to him, "I did not recognise you." He said, "Verily, the patience is at the first stroke of a calamity." ( Sahîh Al-Bukhârî, Hadîth No. 372, Vol. 2)
