Close all doors except the door of Ali’s (ع) house

عَنْ سَعْدِ بْنِ مَالِكٍ أَمَرَ رَسُولُ اللهِ (صلی الله علیه و اله و سلم) بِسَدِّ الْأَبْوَابِ الشَّارِعَةِ فِي الْـمَسْجِدِ وَتَرَكَ بَابَ عَليٍّ (قَالَ الْـهيْثَمِيُّ: رَوَاهُ أَحْمَدُ وَأبُوِ يَعْلَی وَالْبَزَّازُ وَالطَّبَرَانِيُّ فِي الْأَوْسَطِ، وَزادَ: قَالُوا: يَا رَسُولَ اللهِ، سَدَدْتَ أبْوَابَنَا كُلَّهَا إِلَّا بَابَ عَلِيٍّ؟ قَالَ:

﴿ مَا أَنَا سَدَدْتُ أَبْوَابَكُمْ وَلَكِنَّ اللهَ سَدَّهَا ﴾

Saad ibn Malik said: The Messenger of Allah (ص) ordered us to close all the doors of the houses that opened into the mosque but left the door of Ali’s house open.
Haythami writes: This reality has been narrated by Ahmad, Abu Ya’li, Bazzar and Tabarani in Al-Awsat, adding that he said: O Messenger of Allah! You closed our doors and left open the door of Ali's house? The Prophet (ص) said:
"I did not close your doors, but Allah closed them."
