عَنْ أَبِي ذَرٍّ رَضِيَ اللهُ عَنْهُ أَيْضًا: أَنَّ نَاسًا مِنْ أَصْحَابِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالُوا لِلنَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: يَا رَسُولَ اللَّهِ ذَهَبَ أَهْلُ الدُّثُورِ بِالْأُجُورِ، يُصَلُّونَ كَمَا نُصَلِّي، وَيَصُومُونَ كَمَا نَصُومُ، وَيَتَصَدَّقُونَ بِفُضُولِ أَمْوَالِهِمْ، قَالَ: أَوَلَيْسَ قَدْ جَعَلَ اللَّهُ لَكُمْ مَا تَصَّدَّقُونَ؟ إِنَّ بِكُلِّ تَسْبِيحَةٍ صَدَقَةً، وَكُلِّ تَكْبِيرَةٍ صَدَقَةً، وَكُلِّ تَحْمِيدَةٍ صَدَقَةً، وَكُلِّ تَهْلِيلَةٍ صَدَقَةً، وَأَمْرٌ بِالْمَعْرُوفِ صَدَقَةٌ، وَنَهْيٌ عَنْ مُنْكَرٍ صَدَقَةٌ، وَفِي بُضْعِ أَحَدِكُمْ صَدَقَةٌ، قَالُوا: يَا رَسُولَ اللَّهِ أَيَأْتِي أَحَدُنَا شَهْوَتَهُ وَيَكُونُ لَهُ فِيهَا أَجْرٌ؟ قَالَ: أَرَأَيْتُمْ لَوْ وَضَعَهَا فِي حَرَامٍ، أَكَانَ عَلَيْهِ وِزْرٌ؟ فَكَذَلِكَ إِذَا وَضَعَهَا فِي الْحَلَالِ، كَانَ لَهُ أَجْرٌ. رَوَاهُ مُسْلِمٌ

25 – It is also reported on the authority of Abī Dharr (may Allāh be pleased with him):

Some people from amongst the companions of the Messenger of Allāh (peace and blessings of Allāh be upon him) said to the Prophet (peace and blessings of Allāh be upon him): ‘O Messenger of Allāh, the affluent have made off with the rewards; they pray as we pray, they fast as we fast, and they give [much] in charity by virtue of their wealth.’ He (peace and blessings of Allāh be upon him) said: “Has not Allāh made things for you to give in charity? Truly every tasbīḥah [saying: Subḥānallāh] is a charity, and every takbīrah [saying: Allāhu ‘Akbar] is a charity, and every taḥmīdah [saying: Alḥamdulillāh] is a charity, and every tahlīlah [saying: Lā ‘ilāha ‘illallāh] is a charity. And commanding the good is a charity, and forbidding an evil is a charity, and in the bud’i [sexual act] of each one of you there is a charity.” They said: ‘O Messenger of Allāh, when one of us fulfils his carnal desire will he have some reward for that?’ He (peace and blessings of Allāh be upon him) said: “Do you not see that if he were to act upon it [his desire] in an unlawful manner then he would be deserving of punishment? Likewise, if he were to act upon it in a lawful manner then he will be deserving of a reward.” [Reported by Muslim]
