The honorable Companion Huzaifah (Allah be pleased with him) narrates that the Prophet of Allah (blessings and peace of Allah be upon him) said:
“It is not proper for a Believer to disgrace himself.”
It was asked: “O Prophet of Allah ! What is meant by this?”
The Prophet of Allah (blessings and peace of Allah be upon him) said: “To undertake something which you cannot bear.” (Tirmizi)
Hakim al-Umma Mawlana Asharf Ali Thanawi (Allah have mercy on him) explains,
To assume a task beyond one’s capability is not proper for a believer . The consequence will be failure, disgrace, worry, and shame. Frustration will then overtake one.
This saying of the Prophet (hadith) covers all such acts and tasks which are beyond one’s power. In all such cases of difficulties adopt patience (sabr) and supplicate to Allah for aid.
