No doubt, the one that assists in the marriage of two people is looked upon favourably. Marriage is said to be half of faith(religion), we call upon your assistance to help the poor and needy to make it possible to get their daughters married. Sadly having a daughter in poverty stricken countries can be often seen as a burden. Let us lift that burden from these people and remove the hardship. For the one that alleviates a hardship from a person Allaah will alleviate hardship from them.

Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “Whoever relieves the hardship of a believer in this world, Allah will relieve his hardship on the Day of Resurrection. Whoever helps ease one in difficulty, Allah will make it easy for him in this world and the Hereafter. Whoever conceals the faults of a Muslim, Allah will conceal his faults in this world and the Hereafter. Allah helps the servant as long as he helps his brother. Whoever travels a path in search of knowledge, Allah will make easy for him a path to Paradise. People do not gather in the houses of Allah, reciting the Book of Allah and studying it together, but that tranquility will descend upon them, mercy will cover them, angels will surround them, and Allah will mention them to those near Him. Whoever is slow to good deeds will not be hastened by his lineage.”

Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) said: If there was a person who can earn enough for food, drink and shelter, but he needs to get married and he cannot afford to get married, is it permissible to give him zakaah funds so that he can get married? The answer is yes, it is permissible to give him zakaah funds so that he can get married and give a full mahr. If it is said: How come it is permissible to give zakaah funds to a poor person so he can get married even if what is given to him is a large amount? We say: Because a person’s need for marriage is a real need, and in some cases it may be like his need for food and drink. Hence the scholars said: If a person is obliged to spend on someone, he should arrange that person’s marriage if he can afford that. So the father is obliged to arrange his son’s marriage if the son needs to get married but he cannot afford to do so. But I have heard of some fathers who have forgotten how they were when they were young and when the sons ask them for help in getting married, they say: “Get married from your own pocket.” This is not permissible and it is haraam if he able to arrange his marriage. His son will dispute with him on the Day of Resurrection if he did not help him to get married when he was able to. End quote from Fataawa Arkaan al-Islam, p. 440-441.
