Muwatta Malik 1767
موطأ مالك#1767SahihThese are the words of a Companion, not of the Prophet ﷺ. The chain is graded on its own terms.
وَحَدَّثَنِي مَالِكٌ، عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ إِذَا عَطَسَ فَقِيلَ لَهُ يَرْحَمُكَ اللَّهُ . قَالَ يَرْحَمُنَا اللَّهُ وَإِيَّاكُمْ وَيَغْفِرُ لَنَا وَلَكُمْ .
Malik related to me from Nafi that when Abdullah ibn Umar sneezed and someone said to him, "May Allah have mercy on you," (Yarhamuka'llah), he said, "May Allah have mercy on us and you, and forgive us and you." (Yarhamuna'llah wa yaghfirlana wa lakum)
