To give in charity secretly

Narrated Abu Hurairah رضي الله عنه that the Prophet (ﷺ) ﷺ said, “A person who gives in charity so secretly that his left hand does not know what his right hand has given (then he will be under the shade of Allah on the Day of Resurrection).” And the Statement of Allah تعالى: “If you disclose your Sadaqat (alms-giving) it is well, but if you conceal them, and give them to the poor, that is better for you…” (V.2:271).
