[Machine] When the Ansar would go on Hajj, they would not enter their homes through their front doors, but would rather enter from the back of their houses. Allah revealed the following verse: "It is not righteousness that you enter houses from the back, but righteousness is [in] one who fears Allah." [Surah Al-Baqarah 2:189]  

كَانَتِ الْأَنْصَارُ إِذَا حَجَّتْ لَمْ تَدْخُلْ مِنْ أَبْوَابِهَا وَدَخَلَتْ مِنْ ظُهُورِ بُيُوتِهَا فَأَنْزَلَ اللهُ {وَلَيْسَ الْبِرُّ بِأَنْ تَأْتُوا الْبُيُوتَ مِنْ ظُهُورِهَا} [البقرة 189]
