Abu Dharr reported Allah's Apostle (ﷺ) as saying:In the morning charity is due from every bone in the body of every one of you. Every utterance of Allah's glorification is an act of charity. Every utterance of praise of Him is an act of charity, every utterance of profession of His Oneness is an act of charity, every utterance of profession of His Greatness is an act of charity, enjoining good is an act of charity, forbidding what is distreputable is an act of charity, and two rak'ahs which one prays in the forenoon will suffice.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ أَسْمَاءَ الضُّبَعِيُّ، حَدَّثَنَا مَهْدِيٌّ، - وَهُوَ ابْنُ مَيْمُونٍ - حَدَّثَنَا وَاصِلٌ، مَوْلَى أَبِي عُيَيْنَةَ عَنْ يَحْيَى بْنِ عُقَيْلٍ، عَنْ يَحْيَى بْنِ يَعْمَرَ، عَنْ أَبِي الأَسْوَدِ الدُّؤَلِيِّ، عَنْ أَبِي ذَرٍّ، عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ " يُصْبِحُ عَلَى كُلِّ سُلاَمَى مِنْ أَحَدِكُمْ صَدَقَةٌ فَكُلُّ تَسْبِيحَةٍ صَدَقَةٌ وَكُلُّ تَحْمِيدَةٍ صَدَقَةٌ وَكُلُّ تَهْلِيلَةٍ صَدَقَةٌ وَكُلُّ تَكْبِيرَةٍ صَدَقَةٌ وَأَمْرٌ بِالْمَعْرُوفِ صَدَقَةٌ وَنَهْىٌ عَنِ الْمُنْكَرِ صَدَقَةٌ وَيُجْزِئُ مِنْ ذَلِكَ رَكْعَتَانِ يَرْكَعُهُمَا مِنَ الضُّحَى " .
