Surah At-Taubah, Ayat 100

Ayat 100. And the first to embrace Islâm of the Muhajirun (those who migrated from Makkah to Al-Madinah) and the Ansar (the citizens of Al-Madinah who helped and gave aid to the Muhajirun) and also those who followed them exactly (in Faith). Allah is well-pleased with them as they are well-pleased with Him. He has prepared for them Gardens under which rivers flow (Paradise), to dwell therein forever. That is the supreme success.

Hazrat Abu Saeed Al-Khudri (May Allah be pleased with him) said: The Messenger of Allah  [SAWW](PBUH) said, "Allah, the Rubb of honour and glory, will say to the inhabitants of Jannah: `O inhabitants of Jannah!' They will respond: `Here we are! At Your service, O our Rubb. All good is in Your Hand!' He will ask them: `Are you pleased?' They will reply: `Why should we not be pleased, O Rubb, when You have given us what You have not given to any of Your creatures?' Allah will say: `Shall I not give you something better than that?' They will ask: `O Rubb! What can be better than that?' Allah will say: `I shall bestow My Pleasure upon you and I shall never be displeased with you.'' [Al-Bukhari Hadith # 6549].


Lesson : as mentioned above in Surah At-Taubah Ayat 100. " Allah is well-pleased with them as they are well-pleased with Him. ". The declaration about Allah being pleased with the dwellers of Jannah will certainly be the greatest of the boons and rewards of Jannah.
