A man said, "O Allah's Prophet! Who is my father?" The Prophet ﷺ said, "Your father is so-and-so." And then the Divine Verse:-- 'O you who believe! Ask not questions about things..(5.101)  

رَجُلٌ يَا نَبِيَّ اللَّهِ مَنْ أَبِي قَالَ أَبُوكَ فُلاَنٌ وَنَزَلَتْ {يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَسْأَلُوا عَنْ أَشْيَاءَ} الآيَةَ  

that a man said: "O Messenger of Allah! Who is my father?" He said: "Your father is so-and-so." He said: "So (the following) was revealed: O you who believe! Ask not about things which, if made plain to you, may cause you trouble (5:101)."  

رَجُلٌ يَا رَسُولَ اللَّهِ مَنْ أَبِي قَالَ أَبُوكَ فُلاَنٌ فَنَزَلَتْ ( يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَسْأَلُوا عَنْ أَشْيَاءَ إِنْ تُبْدَ لَكُمْ تَسُؤْكُمْ )  

Messenger of Allah, who is my father? And he said: Your father is so and so, and there was revealed this verse:" Do not ask about matters which, if they were to be made manifest to you, might cause you harm" (v. 101). (Using translation from Muslim 2359b)  

رَجُلٌ يَا رَسُولَ اللهِ مَنْ أَبِي؟ قَالَ أَبُوكَ فُلَانٌ فَنَزَلَتْ {يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَسْأَلُوا عَنْ أَشْيَاءَ إِنْ تُبْدَ لَكُمْ تَسُؤْكُمْ} [المائدة 101] إِلَى تَمَامِ الْآيَةَ  

[Machine] "Do you know why this verse was revealed? O you who have believed, do not ask about things that, if they are shown to you, will distress you. There were people who used to mock the Messenger of Allah ﷺ by saying, 'Who is my father?' And he would also say, 'My camel has gone astray, where is my camel?' So Allah revealed this verse."  

أَتَدْرِي فِيمَ أُنْزِلَتْ هَذِهِ الْآيَةُ؟ {يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَسْأَلُوا عَنْ أَشْيَاءَ إِنْ تُبْدَ لَكُمْ تَسُؤْكُمْ} كَانَ أُنَاسٌ يَسْأَلُونَ رَسُولَ اللهِ ﷺ اسْتِهْزَاءً يَقُولُ الرَّجُلُ مَنْ أَبِي؟ وَيَقُولُ ضَلَّتْ نَاقَتِي أَيْنَ نَاقَتِي؟ فَأَنْزَلَ اللهُ هَذِهِ الْآيَةَ
