Suhayb reported,
The Prophet ﷺ said, "When the people of Paradise enter Paradise, Allah 
will say to them, 'Is there anything more you wish for that I may give you?'They will reply, 'Have you not brightened our faces? Have you not admitted us to 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 
."

عن النبي ﷺ قال: إذا دخل أهل الجنة الجنة، قال: يقول الله تبارك وتعالى: تريدون شيئا أزيدكم. فيقولون: ألم تبيض وجوهنا؟ ألم تدخلنا الجنة وتنجنا من النار؟ قال: فيكشف الحجاب، فما أعطوا شيئا أحب إليهم من النظر إلى ربهم عز وجل.
