Muwatta Malik 650
موطأ مالك#650SahihThese are the words of a Companion, not of the Prophet ﷺ. The chain is graded on its own terms.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عَبَّاسٍ، سُئِلَ عَنِ الْقُبْلَةِ، لِلصَّائِمِ فَأَرْخَصَ فِيهَا لِلشَّيْخِ وَكَرِهَهَا لِلشَّابِّ .
Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn Yasar that Abdullah ibn Abbas was asked about people kissing while fasting and he said that he allowed it for old men but disapproved of it for young men
