عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((مَنْ غَسَّلَ مَيِّتًا فَأَدَّى فِيهِ الْأَمَانَةَ، وَلَمْ يُفْشِ عَلَيْهِ مَا يَكُونُ مِنْهُ عِنْدَ ذَلِكَ، خَرَجَ مِنْ ذُنُوبِهِ كَيَوْمِ وَلَدَتْهُ أُمُّهُ))، وَقَالَ: ((لِيَلِيهِ أَقْرَبُكُمْ مِنْهُ، إِنْ كَانَ يَعْلَمُ، فَإِنْ كَانَ لَا يَعْلَمُ فَمَنْ تَرَوْنَ أَنَّ عِنْدَهُ حَظًّا مِنْ وَرَعٍ وَأَمَانَةٍ))
It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: Whoever bathes the deceased, observes trustworthiness in the fulfillment of all related matters, and does not disclose (the private and disliked things) of the deceased, then he becomes as pure from his sins as the day his mother gave birth to him. Then the Prophet (peace and blessings be upon him) said: The close relative of the deceased should be responsible for his affairs, provided he has knowledge (of these matters); otherwise, entrust this responsibility to the one whom you consider to be pious and trustworthy.
