وَمِنْهُم مَّن يَلْمِزُكَ فِى ٱلصَّدَقَٰتِ فَإِنْ أُعْطُوا۟ مِنْهَا رَضُوا۟ وَإِن لَّمْ يُعْطَوْا۟ مِنْهَآ إِذَا هُمْ يَسْخَطُونَ
And of them is he who defameth thee in the matter of the alms. If they are given thereof they are content, and if they are not given thereof, behold! they are enraged.

Chapter: The characteristics of Iblis (Satan) and his soldiers
Narrated Ibn `Abbas:
The Prophet (ﷺ) said, "If anyone of you, on having sexual relation with his wife, says: 'O Allah! Protect me from Satan, and prevent Satan from approaching the offspring you are going to give me,' and if it happens that the lady conceives a child, Satan will neither harm it nor be given power over it."
