QURAN
Surah 3. The Family Of 'Imran, The House Of 'Imran
156. O ye who believe! Be not like the Unbelievers, who say of their brethren, when they are travelling through the Earth or engaged in fighting: "If they had stayed with us, they would not have died, or been slain." This that Allah may make it a cause of sighs and regrets in their hearts. It is Allah that gives Life and Death, and Allah sees well all that ye do.
157. And if ye are slain, or die, in the way of Allah, forgiveness and mercy from Allah are far better than all they could amass.
158. And if ye die, or are slain, Lo! it is unto Allah that ye are brought together.
159. It is part of the Mercy of Allah that thou dost deal gently with them Wert thou severe or harsh-hearted, they would have broken away from about thee: so pass over (Their faults), and ask for ((Allah)'s) forgiveness for them; and consult them in affairs (of moment). Then, when thou hast Taken a decision put thy trust in Allah. For Allah loves those who put their trust (in Him).
160. If Allah helps you, none can overcome you: If He forsakes you, who is there, after that, that can help you? in Allah, then, Let believers put their trust.
