Al-Baqarah

O believers enter into Islam completely and do not follow the footsteps of Shaitãn, surely he is your clear-cut enemy.[208] If you falter after receiving the clear-cut message, then keep in mind that Allah is Mighty, Wise.[209] Are they waiting for Allah to come down to them in the shadow of clouds, along with the angels and make His decision known? Ultimately, all matters will be presented to Allah for decision.[210]

Commandment of entering into Islam completely

SECTION: 26
Ask the Children of Israel how many clear-cut signs We have given them. Anyone who substitutes the favor of Allah (changes the revelations of Allah) after it has come to him, should know that Allah is strict in retribution.[211] The life of this world is charming to those who are unbelievers and they mock at those who believe, but they forget that those who fear Allah will rank above them on the Day of Resurrection; Allah gives sustenance without measure to whom He wants.[212]

Believers will rank above the disbelievers on the Day of Judgement

Mankind was one nation having one religion. Later when people invented other religions, Allah appointed Prophets as bearers of good news and warnings; and revealed to them the Book with the True Guidance to settle the matters of dispute between mankind. But the very people to whom it was given, started disputes after the clear arguments had come to them, because of rivalry between one another. Allah has guided the believers by His will to the truth in those matters in which they had differences. Allah guides whom He pleases towards the Right Way.[213]

Do you think that you will enter Paradise without any trials while you have known the examples of those who passed away before you? They were afflicted with suffering and adversity and were so violently shaken up that even the Rasool and the believers with him cried out: “When will Allah’s help come?” Then they were comforted with the words, Be aware! Allah’s help is ever close.[214]

The way to Paradise passes through trials

They ask you what they should spend in charity. Say: “Whatever you spend with a good heart, give it to parents, relatives, orphans, the helpless, and travellers in need. Whatever good you do, Allah is aware of it.[215] Fighting has been made obligatory for you, much to your dislike. It is quite possible that something which you don’t like is good for you and that something which you love is bad for you. Allah knows, and you do not.[216]

Charity and fighting (for just cause) is made obligatory

SECTION: 27 They ask you about war in the Sacred Month. Tell them: "Fighting in this month is a heinous offence; but to prevent from the path of Allah, to deny Him, to prevent access and expel His worshippers from the Sacred Mosque is a more severe crime, since mischief is worse than killing in His sight. As for unbelievers: they will not cease fighting until they succeed in turning you back from your religion if they can; and if any of you turns back from his religion and dies as an unbeliever, his deeds will become void in this life and in the hereafter. He will be the inmate of the hellfire, to live in there forever.[217] Surely those who are believers, and migrated and struggled in the path of Allah, they can hope for the mercy of Allah; and Allah is Forgiving, Merciful."[218]

Fighting during the Sacred Months is a heinous sin
