Quran Chapter 2 Verse 214-217
Or do you think that you will enter Paradise while such [trial] has not yet come to you as came to those who passed on before you? They were touched by poverty and hardship and were shaken until [even their] messenger and those who believed with him said,”When is the help of Allah ?” Unquestionably, the help of Allah is near.
They ask you, [O Muhammad], what they should spend. Say, “Whatever you spend of good is [to be] for parents and relatives and orphans and the needy and the traveler. And whatever you do of good – indeed, Allah is Knowing of it.”
Fighting has been enjoined upon you while it is hateful to you. But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah Knows, while you know not.
They ask you about the sacred month – about fighting therein. Say, “Fighting therein is great [sin], but averting [people] from the way of Allah and disbelief in Him and [preventing access to] al-Masjid al-Haram and the expulsion of its people therefrom are greater [evil] in the sight of Allah . And fitnah is greater than killing.” And they will continue to fight you until they turn you back from your religion if they are able. And whoever of you reverts from his religion [to disbelief] and dies while he is a disbeliever – for those, their deeds have become worthless in this world and the Hereafter, and those are the companions of the Fire, they will abide therein eternally.
