(107) باب مَا يُقَالُ عِنْدَ النَّوْمِ
Hudhaifah said :
when the prophet (May peace be upon him) lay down on his bed (at night), he would say: O Allah! In Thy name I die and live. When he awoke, he said: praise be to Allah who has given us life after causing us to die and to whom we shall be resurrected.
