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.

Fasting
Chapter: Fasting the last days of the month
Narrated Mutarrif from `Imran Ibn Husain:
That the Prophet (ﷺ) asked him (Imran) or asked a man and `Imran was listening, "O Abu so-and-so! Have you fasted the last days of this month?" (The narrator thought that he said, "the month of Ramadan"). The man replied, "No, O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) said to him, "When you finish your fasting (of Ramadan) fast two days (in Shawwal)." Through another series of narrators `Imran said, "The Prophet (ﷺ) said, '(Have you fasted) the last days of Sha'ban?"
