When I get some money from my father or mother, I give it in charity and keep a little. When I ask them for money they say, “Where did your money go?” I tell them a lie and say that I bought stuff with it. The reason why I tell this lie is that I want Allaah to increase their good deeds. Is it permissible for me to lie to them or should I tell them the truth?.
The basic principle concerning telling lies is that it is one of the signs of the hypocrites, because the Prophet (peace and blessings of Allaah be upon him) said: “The signs of the hypocrite are three: when he speaks, he lies, when he makes a promise he breaks it, and when he is entrusted with something he breaks that trust.” Narrated by al-Bukhaari, 32; Muslim, 89.
But there are some instances in which Islam permits lying, if that serves a greater purpose or wards off a greater harm:
These cases include the following:
1- When a person is intermediating in order to bring about reconciliation between two disputing parties.
2- When a man speaks to his wife, or a wife to her husband, concerning matters that will increase the love between them.
It was narrated from Umm Kulthoom bint ‘Uqbah that she heard the Messenger of Allaah (peace and blessings of Allaah be upon him) say: “He is not a liar who brings about reconciliation among people, conveys good words and says good things.”
Narrated by al-Bukhaari, 2546; Muslim, 2605
It was narrated that Asma’ bint Yazeed said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Lies are not appropriate except in three cases: when a man speaks to his wife to please her, telling lies at times of war, and lying in order to bring about reconciliation between people.”
Shaykh al-Albaani said: it is hasan.
What you have mentioned is no excuse for telling lies to your family. If you are honest with them they will never be deprived of the reward for spending on you. And you can combine your family’s spending on you and their giving in charity to the needy by encouraging them to spend for the sake of Allaah, with no need to tell lies about buying stuff when you have not done so.
We ask Allaah to correct your intention and set your affairs straight, and to reward you greatly for your desire to benefit your family.
And Allaah knows best.
