Small Charity

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.”
(Bukhari)

The Importance of Being Patient

Abu Sa`id and Abu Hurairah (May Allah be pleased with him) reported that the Prophet (peace and blessings of Allah be upon him) said: "Never a believer is stricken with a discomfort, an illness, an anxiety, a grief or mental worry or even the pricking of a thorn but Allah will expiate his sins on account of his patience". [Al-Bukhari and Muslim]

Commentary: This Hadith mentions the special Grace and Mercy of Allah for the Muslims. It relates how Allah turns the hardships and troubles suffered by a Muslim into a means of expiation for his sins. But this is only possible if the believer exercises patience. However, if he starts wailing instead of showing patience then beside suffering hardships, he would be deprived of the reward which lies in bearing them patiently. Thus, he shall have to take the burden of additional sins also.
