Some people were asking Messenger of Allah ﷺ questions mockingly. A man would say, "Who is my father?" Another man whose she-camel had gone astray would say, "Where is my she-camel? "So Allah revealed this Verse in this connection: "O you who believe! Ask not about things which, if made plain to you, may cause you trouble." (5.101)  

كَانَ قَوْمٌ يَسْأَلُونَ رَسُولَ اللَّهِ ﷺ اسْتِهْزَاءً فَيَقُولُ الرَّجُلُ مَنْ أَبِي وَيَقُولُ الرَّجُلُ تَضِلُّ نَاقَتُهُ أَيْنَ نَاقَتِي فَأَنْزَلَ اللَّهُ فِيهِمْ هَذِهِ الآيَةَ {يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَسْأَلُوا عَنْ أَشْيَاءَ إِنْ تُبْدَ لَكُمْ تَسُؤْكُمْ} حَتَّى فَرَغَ مِنَ الآيَةِ كُلِّهَا  

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).  

رَجُلٌ يَا رَسُولَ اللَّهِ مَنْ أَبِي قَالَ أَبُوكَ فُلاَنٌ وَنَزَلَتْ { يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَسْأَلُوا عَنْ أَشْيَاءَ إِنْ تُبْدَ لَكُمْ تَسُؤْكُمْ} تَمَامَ الآيَةِ  

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
