Yahya related to me from Malik from Ibn Shihab from Abu Bakr ibnSulayman ibn Abi Hathma that Umar ibn al-Khattab missed Sulayman ibnAbi Hathma in the subh prayer. In the morning he went to the market,and Sulayman's house was between the market and the Prophet's mosque.He passed ash-Shifa, Sulayman's mother, and said to her, "I did notsee Sulayman at subh." She replied, "He spent the night in prayer andhis eyes overcame him. Umar said, "I would rather be present at subhthan stand the whole night in prayer.
