Shaikh ul Hadith (Rahmatullah Alaihe) has written that if one’s parents have passed away whilst they were upset with him, then what should he do to please them? Listen to the formula. Rasulullah (Sallellaho Alaihe Wasallam) said, “Whoever’s parents have passed away and they had caused difficulty to them, but were guided thereafter, then these disobedient children should make dua of forgiveness on behalf of their parents. Seek forgiveness from Allah Ta'ala and continue sending them the reward of your optional acts of worship. They should give charity, recite the Qur’an and thereafter convey the rewards to them. On the Day of Judgment, Allah Ta’ala will record them as obedient children. This Hadith is being presented to you so that none of you become despondent. It is possible that such a person is present in this gathering who has shown disrespect to his parents and they left the world displeased with him. He can compensate for this. For the remainder of his life, he should continue conveying rewards to them by means of optional worship and charity. On the Day of Judgment, Allah Ta'ala will forgive him and record him amongst the obedient children. Subhanallah! How much is not Allah Ta’ala‘s mercy that He does not keep His servant despondent in any condition.
