(51) باب صِفَةِ الْجَنَّةِ وَالنَّارِ
Narrated Abu Sa`id Al-Khudri:
Allah's Messenger (ﷺ) said, "Allah will say to the people of Paradise, 'O the people of Paradise!' They will say, 'Labbaik, O our Lord, and Sa`daik!' Allah will say, 'Are you pleased?" They will say, 'Why should we not be pleased since You have given us what You have not given to anyone of Your creation?' Allah will say, 'I will give you something better than that.' They will reply, 'O our Lord! And what is better than that?' Allah will say, 'I will bestow My pleasure and contentment upon you so that I will never be angry with you after for-ever.' "
