وَلَا تُلْقُوا بِأَيْدِيكُمْ إِلَى التَّهْلُكَةِ
Do not cast yourselves into destruction by your own hands. (2:195)
Abū Ayyūb al-Anṣārī explained its context: some of the Anṣār considered turning to their property and occupations instead of continuing their participation in struggle.
The reported occasion clarifies the warning beyond a superficial reading of the words.
