كتاب الصلاة

Prayer

Yahya related to me from Malik from his paternal uncle Abu Suhayl ibn Malik that his uncle's father said, "I recognise nothing nowadays of what I saw the people (i.e. the companions of the Messenger, may Allah bless him and grant him peace ) doing except the call to prayer."

وَحَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ عَمِّهِ أَبِي سُهَيْلِ بْنِ مَالِكٍ، عَنْ أَبِيهِ، أَنَّهُ قَالَ مَا أَعْرِفُ شَيْئًا مِمَّا أَدْرَكْتُ عَلَيْهِ النَّاسَ إِلاَّ النِّدَاءَ بِالصَّلاَةِ ‏.‏
