Muwatta Malik, Book 20, Hadith 135 (USC-MSA) ⓘ
Yahya related to me from Malik from Abu'n-Nadr, the mawla of Umar ibn Ubaydullah, from Sulayman ibn Yasar that the Messenger of Allah, may Allah bless him and grant him peace, forbade fasting on the days of Mina.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ أَبِي النَّضْرِ، مَوْلَى عُمَرَ بْنِ عُبَيْدِ اللَّهِ عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، . أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ صِيَامِ أَيَّامِ مِنًى .
