Suhayb reported,
The Prophet ﷺ said, "When the people of Paradise enter Paradise, Allah 
will say, 'Do you wish for anything more that I may add for you?'They will reply, 'Have You not whitened our faces? Have You not admitted us into Paradise and saved us from the Fire?'Then He will lift the veil, and nothing they have been given will be more beloved to them than gazing upon their Lord 
."

Sahihعن صهيب
عن النبي ﷺ قال: إذا دخل أهل الجنة الجنة. قال: يقول الله تبارك وتعالى: تريدون شيئا أزيدكم؟ فيقولون: ألم تبيض وجوهنا؟ ألم تدخلنا الجنة، وتنجينا من النار؟ قال: فيكشف الحجاب. فما أعطوا شيئا أحب إليهم من النظر إلى ربهم عز وجل.
Muslim reported it in the Book of Faith (181) from Ubaydullah bin Umar bin Maysara, who said, Abdul-Rahman bin Mahdi narrated to me, Hammad bin Salama narrated to us, from Thabit Bunani, from Abdul-Rahman bin Abu Layla, from Suhayb, and he related the hadith.He also reported it through the route of Yazid bin Harun, from Hammad bin Salama, with this same chain, adding, "Then he recited this verse, "For those who did good is the best reward and even more" [Yunus 10:26]."A number of scholars among the companions and the successors have stated regarding the words of Allah, Most High, "For those who did good is the best reward and even more", that the "more" refers to looking upon the face of their Lord . Ibn Khuzayma mentioned this in his book Tawhid (1/402-403) and attributed it to a number of scholars.
