A: A Muslim rescuing other Muslims or non­combatant Kafirs (disbelievers/non­Muslims) does not become a brother to them. If the person being rescued is a woman, the rescuer does not become a Mahram (an unmarriageable relative) to her. Such act is rewarded for it is an act of kindness, even if the one rescued is a Kafir. Allah (Glorified and Exalted be He) says: and do good. Truly, Allâh loves Al­Muhsinûn (the good­doers). He (Glorified and Exalted be He) also says: Allâh does not forbid you to deal justly and kindly with those who fought not against you on account of religion nor drove you out of your homes. Verily, Allâh loves those who deal with equity. The Prophet (peace be upon him) said: Allah continues to help His Servant as long as the servant helps his brother. He (peace be upon him) also said: Whoever fulfills the needs of his brother, Allah will fulfill his needs. These two Hadith are related to Muslims. It was reported in the Two Sahih (authentic) Books of Hadith (i.e. Al­Bukhari and Muslim) on the authority of Asma' bint Abu Bakr (may Allah be pleased with both of them) that the Prophet (peace be upon him) allowed her to keep good relations with her Kafir mother at the time of the truce that took place between the Prophet (peace be upon him) and the people of Makkah. Concerning combatant Kafirs, it is not permissible to help them in any way; rather, helping them is one of the acts which nullifies Islam. Allah (Glorified and Exalted be He) says: nd if any amongst you takes them as Auliyâ', then surely he is one of them.
