Q: My son used to give me his salary willingly for several months. One day, I became angry with him and told him, "Your salary shall be unlawful for me like my mother." Please advise me. May Allah protect you.

A: You are required to offer Kaffarah (expiation) for an oath, which is either to feed ten Miskins (needy persons); each Miskin half a Sa` (1 Sa`=3 kg. Approx.) of food, that is approximately one and half kilograms for each one, or to provide each Miskin with clothing such as a shirt or a garment, or to emancipate a believing slave. If you are unable to afford any of these three options, you must observe Sawm (Fast) for three days. This is because rendering the Halal (lawful) as Haram (prohibited) is like an oath, for Allah (Exalted be He) says: O Prophet! Why do you forbid (for yourself) that which Allâh has allowed to you until the following Ayah (Qur'anic verse): Allâh has already ordained for you (O men) the absolution from your oaths. The salary (Part No. 20; Page No. 314) of your son will not be unlawful for you, but if you take it, you should offer the Kaffarah as has already been outlined. Moreover, you must make Tawbah (repentance to Allah) because it is not permissible to render the Halal as Haram. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
