What to say when one is angry or harsh for Allah‘s sake

Narrated 'Aisha:

The Prophet entered upon me while there was a curtain having pictures (of animals) in the house. His face got red with anger, and then he got hold of the curtain and tore it into pieces. The Prophet ﷺ said, "Such people as paint these pictures will receive the severest punishment on the Day of Resurrection ."

حَدَّثَنَا يَسَرَةُ بْنُ صَفْوَانَ، حَدَّثَنَا إِبْرَاهِيمُ، عَنِ الزُّهْرِيِّ، عَنِ الْقَاسِمِ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ دَخَلَ عَلَىَّ النَّبِيُّ ﷺ وَفِي الْبَيْتِ قِرَامٌ فِيهِ صُوَرٌ، فَتَلَوَّنَ وَجْهُهُ، ثُمَّ تَنَاوَلَ السِّتْرَ فَهَتَكَهُ، وَقَالَتْ قَالَ النَّبِيُّ ﷺ " مِنْ أَشَدِّ النَّاسِ عَذَابًا يَوْمَ الْقِيَامَةِ الَّذِينَ يُصَوِّرُونَ هَذِهِ الصُّوَرَ ".

Narrated Abu Mas'ud:

A man came to the Prophet and said "I keep away from the morning prayer only because such and such person prolongs the prayer when he leads us in it. The narrator added: I had never seen Allah's Apostle more furious in giving advice than he was on that day. He said, "O people! There are some among you who make others dislike good deeds) cause the others to have aversion (to congregational prayers). Beware! Whoever among you leads the people in prayer should not prolong it, because among them there are the sick, the old, and the needy." (See Hadith No. 670, Vol 1)

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ، حَدَّثَنَا قَيْسُ بْنُ أَبِي حَازِمٍ، عَنْ أَبِي مَسْعُودٍ ـ رضى الله عنه ـ قَالَ أَتَى رَجُلٌ النَّبِيَّ ﷺ فَقَالَ إِنِّي لأَتَأَخَّرُ عَنْ صَلاَةِ الْغَدَاةِ مِنْ أَجْلِ فُلاَنٍ مِمَّا يُطِيلُ بِنَا قَالَ فَمَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ قَطُّ أَشَدَّ غَضَبًا فِي مَوْعِظَةٍ مِنْهُ يَوْمَئِذٍ قَالَ فَقَالَ " يَا أَيُّهَا النَّاسُ إِنَّ مِنْكُمْ مُنَفِّرِينَ، فَأَيُّكُمْ مَا صَلَّى بِالنَّاسِ فَلْيَتَجَوَّزْ، فَإِنَّ فِيهِمُ الْمَرِيضَ وَالْكَبِيرَ وَذَا الْحَاجَةِ ".

Narrated 'Abdullah bin 'Umar:

While the Prophet was praying, he saw sputum (on the wall) of the mosque, in the direction of the Qibla, and so he scraped it off with his hand, and the sign of disgust (was apparent from his face) and then said, "Whenever anyone of you is in prayer, he should not spit in front of him (in prayer) because Allah is in front of him."

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جُوَيْرِيَةُ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ بَيْنَا النَّبِيُّ ﷺ يُصَلِّي رَأَى فِي قِبْلَةِ الْمَسْجِدِ نُخَامَةً، فَحَكَّهَا بِيَدِهِ، فَتَغَيَّظَ ثُمَّ قَالَ " إِنَّ أَحَدَكُمْ إِذَا كَانَ فِي الصَّلاَةِ فَإِنَّ اللَّهَ حِيَالَ وَجْهِهِ، فَلاَ يَتَنَخَّمَنَّ حِيَالَ وَجْهِهِ فِي الصَّلاَةِ ".

Narrated Zaid bin Khalid Al-Juhani:

A man asked Allah's Apostle about "Al-Luqata" (a lost fallen purse or a thing picked up by somebody). The Prophet ﷺ said, "You should announce it publicly for one year, and then remember and recognize the tying material of its container, and then you can spend it. If its owner came to you, then you should pay him its equivalent." The man said, "O Allah's Apostle! What about a lost sheep?" The Prophet ﷺ said, "Take it because it is for you, for your brother, or for the wolf." The man again said, "O Allah's Apostle! What about a lost camel?" Allah's Apostle became very angry and furious and his cheeks became red (or his face became red), and he said, "You have nothing to do with it (the camel) for it has its food and its water container with it till it meets its owner."

حَدَّثَنَا مُحَمَّدٌ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، أَخْبَرَنَا رَبِيعَةُ بْنُ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ يَزِيدَ، مَوْلَى الْمُنْبَعِثِ عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، أَنَّ رَجُلاً، سَأَلَ رَسُولَ اللَّهِ ﷺ عَنِ اللُّقَطَةِ فَقَالَ " عَرِّفْهَا سَنَةً، ثُمَّ اعْرِفْ وِكَاءَهَا وَعِفَاصَهَا، ثُمَّ اسْتَنْفِقْ بِهَا، فَإِنْ جَاءَ رَبُّهَا فَأَدِّهَا إِلَيْهِ ". قَالَ يَا رَسُولَ اللَّهِ فَضَالَّةُ الْغَنَمِ قَالَ " خُذْهَا، فَإِنَّمَا هِيَ لَكَ، أَوْ لأَخِيكَ، أَوْ لِلذِّئْبِ ". قَالَ يَا رَسُولَ اللَّهِ فَضَالَّةُ الإِبِلِ قَالَ فَغَضِبَ رَسُولُ اللَّهِ ﷺ حَتَّى احْمَرَّتْ وَجْنَتَاهُ ـ أَوِ احْمَرَّ وَجْهُهُ ـ ثُمَّ قَالَ " مَالَكَ وَلَهَا، مَعَهَا حِذَاؤُهَا وَسِقَاؤُهَا، حَتَّى يَلْقَاهَا رَبُّهَا ".
