There are many authentic ahadith which are in sync with the Quranic rulings on charity. Here are some of them:
Abdullah al-khaulani reported that when Uthman bin Affan tried to rebuild the mosque of Prophet Mohammad (saw) the people began to talk about this. Uthman bin Affan said that you discuss it very much where as I have heard Allah’s Messenger (saw) as saying, ‘He who builds a mosque and the narrator said ‘I think he also said that seeking the pleasure of Allah, Allah would build (a similar house for him in Paradise) and in the narration of Harun (the words are) ‘A house for him in Paradise’. (Sahih Muslim).
‘Whoever contributes in building a mosque for Allah (swt) even if it is as tiny as a bird’s nest, Allah (swt) will build for him a house in Paradise. (Ahmad)
Prophet Mohammad (saw) said, ‘The virtuous deeds that will reach a believer after his death are: knowledge which he attained and then imparted to others, a virtuous son which he leaves behind, a copy of the Quran which he leaves as a legacy, a mosque that he had built, a house which he constructed for the travelers, a canal that he dug or the charity that he offered during his lifetime when he was in good health, these deeds will reach him after his death’. (Classed as good by Saheeh Ibn Maajah).
Prophet Mohammad (saw) said, Nothing shall ascertain the welfare (and interests) of your religion besides generosity and good character.
Jabir Ibn-e-Abdullah Ansari narrated that Prophet Mohammad (saw) never disappointed anybody who asked him for help.
Prophet Mohammad (saw) said that ‘The Awlia, Friends of Allah (swt) are essentially and inherently generous.
So we find, that the donation that we offer for charitable purposes, is a means of obtaining the Goodwill of Allah (swt) in this world and the Hereafter. Donation not only helps to purify one’s wealth but it also helps in the realization of the Islamic goal of establishing an egalitarian society, which is free from all sorts of injustice and dishonesty.
Keep Me In Your Prayers.
