The Prophet (peace and blessings of Allah be upon him) advised to give even a small amount in charity as he said: “Protect yourselves from the Fire even if it is with half a date.” (Bukhari, Muslim)
Furthermore, the following hadith demonstrates the beauty and greatness of giving in charity, even in small amounts:
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.”
