that a man from the people of Al-'Iraq asked Ibn 'Umar about the blood of a gnat that gets on the clothes. Ibn 'Umar said "Look at this one, he asks about the blood of a gnat while they killed the son of the Messenger of Allah ﷺ! And I heard the Messenger of Allah ﷺ said: 'Indeed Al-Hasan and Al-Husain - they are my two sweet basils in the world.'"
أَنَّ رَجُلاً مِنْ أَهْلِ الْعِرَاقِ سَأَلَ ابْنَ عُمَرَ عَنْ دَمِ الْبَعُوضِ يُصِيبُ الثَّوْبَ فَقَالَ ابْنُ عُمَرَ انْظُرُوا إِلَى هَذَا يَسْأَلُ عَنْ دَمِ الْبَعُوضِ وَقَدْ قَتَلُوا ابْنَ رَسُولِ اللَّهِ ﷺ وَسَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ: «إِنَّ الْحَسَنَ وَالْحُسَيْنَ هُمَا رَيْحَانَتَاىَ مِنَ الدُّنْيَا.»
