Ibn Abi Nu'm said, "I was with Ibn 'Umar when a man asked him about the blood of gnats. He asked, 'Where are you from?' 'From the people of Iraq,' he replied. He said, 'Look at this man! He asks about the blood of gnats when they murdered the grandson of the Prophet, may Allah bless him and grant him peace! I heard the Prophet ﷺ say, 'They are my sweet basil in this world.'"

كُنْتُ شَاهِدًا ابْنَ عُمَرَ إِذْ سَأَلَهُ رَجُلٌ عَنْ دَمِ الْبَعُوضَةِ؟ فَقَالَ مِمَّنْ أَنْتَ؟ فَقَالَ مِنْ أَهْلِ الْعِرَاقِ فَقَالَ انْظُرُوا إِلَى هَذَا يَسْأَلُنِي عَنْ دَمِ الْبَعُوضَةِ وَقَدْ قَتَلُوا ابْنَ النَّبِيِّ ﷺ سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ هُمَا رَيْحَانَيَّ مِنَ الدُّنْيَا

A man from the people of Iraq asked Ibn Umar ᴿᴬ about ˹a ruling on˺ the blood of mosquitoes that gets on a garment. Ibn Umar ᴿᴬ said: Look at this one: he asks about the blood of mosquitoes, while they have killed the son of the Messenger of Allah ﷺ! I heard the Messenger of Allah ﷺ say: "Indeed, al-Hasan and al-Husayn are my two fragrant flowers from this 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.»

"عن ابن أنعْم قَالَ: كُنْتُ جَالِسًا عِند ابن عُمَرَ، فأَتَاهُ رَجُلٌ فَسأَلَهُ عَنْ دَمِّ البعُوضِ؟ فَقَالَ لَهُ ابنُ عُمَرَ: مِمَّنْ أَنْتَ؟ فَقَالَ: رَجُلٌ مِنْ أَهْلِ العِرَاقِ، فَقَالَ ابْنُ عُمَرَ: هَا! اُنْظُرُوا هَذا يَسْألُنى عَنْ دمِّ البَعُوضِ وهُمْ قَتَلُوا ابنَ رسُولِ اللهِ ﷺ وَسَمِعْتُ رَسُول اللهِ ﷺ يَقُولُ: هُمَا رَيَحْانَتَاى مِنَ الدُّنْيَا".
