Muhammad bin Ibrahim says that Abu Salamah bin Abdur Rahman and Sulaiman bin Yasar both narrated to him this hadith of Sayyiduna Ibn Umar (may Allah be pleased with them). Although I was also present with them in that gathering, I was a small child, so I could not remember it. That a man asked Sayyiduna Ibn Umar (may Allah be pleased with them) about the Witr prayer? And he narrated the complete hadith. Sayyiduna Ibn Umar (may Allah be pleased with them) said: The Prophet (peace and blessings be upon him) commanded that the last prayer of the night should be made Witr.
