مُوَطَّأُ مَالِكٍ
Muwatta Malik 155
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 .
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, (ﷺ) ) doing except the call to prayer."
