Hadith 9: Responsibility within one’s capacity التكليف بما يستطاع
Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said:
مَا نَهَيْتُكُمْ عَنْهُ فَاجْتَنِبُوهُ وَمَا أَمَرْتُكُمْ بِهِ فَافْعَلُوا مِنْهُ مَا اسْتَطَعْتُمْ فَإِنَّمَا أَهْلَكَ الَّذِينَ مِنْ قَبْلِكُمْ كَثْرَةُ مَسَائِلِهِمْ وَاخْتِلَافُهُمْ عَلَى أَنْبِيَائِهِمْ
What I have prohibited for you, avoid it. What I have commanded you, do it as much as you can. Verily, those before you were ruined only due to their excessive questioning and contradicting their prophets.

In another narration, the Prophet said:
اتْرُكُونِي مَا تَرَكْتُكُمْ فَإِذَا حَدَّثْتُكُمْ فَخُذُوا عَنِّي فَإِنَّمَا هَلَكَ مَنْ كَانَ قَبْلَكُمْ بِكَثْرَةِ سُؤَالِهِمْ وَاخْتِلَافِهِمْ عَلَى أَنْبِيَائِهِمْ
Leave me with what I have left you. When I narrate a saying to you, take it from me. Verily, those before you were ruined only due to their excessive questioning and contradicting their prophets.
