It is narrated from Abu Qilabah (may Allah have mercy on him) that Sayyiduna Malik bin al-Huwayrith al-Laythi (may Allah be pleased with him) informed us that he saw the Messenger of Allah (peace and blessings be upon him) praying; when he (peace and blessings be upon him) was in an odd-numbered rak'ah of his prayer, he would not stand up until he had sat up straight.
