Anas reported: The Prophet, peace and blessings be upon him, said, “No Muslim servant visits his brother for the sake of Allah but that a caller from the heavens announces: You are purified and Paradise is purified for you! Otherwise, Allah says in the realms of His throne: My servant has visited Me and his guest for My sake, so I am not pleased for him to have any reward other than Paradise.”

عَن أَنَس عَن النَّبِيّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَا مِنْ عَبْدٍ مُسْلِمٍ أَتَى أَخًا لَهُ يَزُورُهُ فِي اللَّهِ إلاَّ نَادَاهُ مُنَادٍ مِنَ السَّمَاءِ أَنْ طِبْتَ وَطَابَتْ لَكَ الْجَنَّةُ وَإِلَّا قَالَ اللَّهُ فِي مَلَكُوتِ عَرْشِهِ عَبْدِي زَارَ فِيَّ وَعَلَيَّ قِرَاهُ فَلَمْ يَرْضَ اللَّهُ لَهُ بِثَوَابٍ دُونَ الْجَنَّةِ
