باب فَضْلِ إِخْفَاءِ الصَّدَقَةِ ‏

Abu Huraira reported that the Messenger of Allah (ﷺ) had said:

Seven are (the persons) whom Allah would give protection with His Shade on the Day when there would be no shade but that of Him (i. e. on the Day of Judgment, and they are): a just ruler, a youth who grew up with the worship of Allah; a person whose heart is attached to the mosques; two persons who love and meet each other and depart from each other for the sake of Allah; a man whom a beautiful woman of high rank seduces (for illicit relation), but he (rejects this offer by saying):" I fear Allah" ; a person who gives charity and conceals it (to such an extent) that the right hand does not know what the left has given: and a person who remembered Allah in privacy and his eyes shed tears.
حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، جَمِيعًا عَنْ يَحْيَى الْقَطَّانِ، - قَالَ زُهَيْرٌ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، - عَنْ عُبَيْدِ اللَّهِ، أَخْبَرَنِي خُبَيْبُ بْنُ عَبْدِ الرَّحْمَنِ، عَنْ حَفْصِ بْنِ عَاصِمٍ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ سَبْعَةٌ يُظِلُّهُمُ اللَّهُ فِي ظِلِّهِ يَوْمَ لاَ ظِلَّ إِلاَّ ظِلُّهُ الإِمَامُ الْعَادِلُ وَشَابٌّ نَشَأَ بِعِبَادَةِ اللَّهِ وَرَجُلٌ قَلْبُهُ مُعَلَّقٌ فِي الْمَسَاجِدِ وَرَجُلاَنِ تَحَابَّا فِي اللَّهِ اجْتَمَعَا عَلَيْهِ وَتَفَرَّقَا عَلَيْهِ وَرَجُلٌ دَعَتْهُ امْرَأَةٌ ذَاتُ مَنْصِبٍ وَجَمَالٍ فَقَالَ إِنِّي أَخَافُ اللَّهَ ‏.‏ وَرَجُلٌ تَصَدَّقَ بِصَدَقَةٍ فَأَخْفَاهَا حَتَّى لاَ تَعْلَمَ يَمِينُهُ مَا تُنْفِقُ شِمَالُهُ وَرَجُلٌ ذَكَرَ اللَّهَ خَالِيًا فَفَاضَتْ عَيْنَاهُ ‏"‏ ‏.‏
