question #1 Sahih al-Bukhari 7503, Book 97, Hadith 128 : How does rain serve as a sign of belief or disbelief in Allah according to Islamic teachings?

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.’”
