And those who believed and did righteous deeds will be admitted to gardens beneath which rivers flow, abiding eternally therein by permission of their Lord; and their greeting therein will be, "Peace!"
Shaytan disowns His Followers on the Day of Resurrection
Allah narrates to us what Iblis will say to his followers after Allah finishes with the judgement between His servants, sending the believers to the gardens of Paradise and the disbelievers to the lows (of the Fire). Iblis, may Allah curse him, will stand and address the latter, in order to add depression to their depression, sorrow to their sorrow and grief to their grief. He will declare,
إِنَّ اللَّهَ وَعَدَكُمْ وَعْدَ الْحَقِّ
`(Verily, Allah promised you a promise of truth.) by the words of His Messengers that if you follow them, you will gain safety and deliverance. Truly, Allah's promise was true and correct news, while I promised you then betrayed you.' Allah said in another Ayah,
In the last verse here (8), it was said: قَالَ مُوسَىٰ إِن تَكْفُرُوا أَنتُمْ وَمَن فِي الْأَرْضِ جَمِيعًا (And Musa said, "If you are ungrateful, you and all those on earth, then, Allah is free of all needs, worthy of every praise.) " This was said by Sayyidna Musa (علیہ السلام) to his people. He is telling them that should they or, for that matter, all inhabitants of the earth become ungrateful to Allah Ta’ ala, it is not going to cause any loss to Allah Ta’ ala. As for Him, He needs no praise or gratitude for Himself. He is Independent. He is beyond that. He is intrinsically Praised and deserving of praise. If you do not praise Him, the angels do, all of them, and so does every particle of this universe.
So, whatever good there is in gratitude, that is for you alone. There-fore, when you are asked to be grateful by Allah Ta’ ala, there is no gain for Him in doing so. In fact, it is His infinite mercy reaching out to you in your interest.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 23–25
To say assalamu alaykum or ‘peace be with you’ at the time of meeting is not simply a formal social custom. This is in fact an outward symbol of a heartfelt connection. Those who have lived their lives in this world with feelings of benevolence towards others, who have known how to forget their grievances and love others wholeheartedly, who have always spoken of others with respect, who have chosen for others what they desired for themselves, who have always longed in their heart of hearts for the well-being of others and who have rejoiced in seeing others in a state of well-being—such will be the people who will be entitled to take up their abode in the splendid world of paradise. The greeting assalamu alaykum has always given expression to their feelings of love and well-wishing whenever they met their brothers; in the Hereafter, when they greet their heavenly neighbours, this salutation will assume a powerful and more aesthetic form.
