Narrated `Adi bin Hatim heard the the Prophet (ﷺ) saying:
“ اتَّقُوا النَّارَ وَلَوْ بِشِقِّ تَمْرَةٍ ”
“Save yourself from Hell-fire even by giving half a date-fruit in charity.”
(Sahih al-Bukhari 1417)
It is mustahabb to give charity to one who is in need, even if it is something small.
It was narrated that Abu Hurayrah (may Allah be pleased with him) said: The Messenger of Allah (blessings and peace of Allah be upon him) said: “Whoever gives charity the equivalent of a date that was acquired by halaal means – for Allah does not accept anything but that which is good (halaal)– Allah accepts it in His right hand, then He tends it for the one who gave it, as one of you tends his foal, until it becomes like a mountain.”
