Narrated Zaid bin Khalid:

It rained (because of the Prophet's invocation for rain) and the Prophet ﷺ said, "Allah said, 'Some of My slaves have become disbelievers in Me, and some others, believers in Me.'"

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، عَنْ صَالِحٍ، عَنْ عُبَيْدِ اللَّهِ، عَنْ زَيْدِ بْنِ خَالِدٍ، قَالَ مُطِرَ النَّبِيُّ ﷺ فَقَالَ " قَالَ اللَّهُ أَصْبَحَ مِنْ عِبَادِي كَافِرٌ بِي وَمُؤْمِنٌ بِي ".
