Al Baqarah Ayah 189

۞ يَسْــَٔلُونَكَ عَنِ ٱلْأَهِلَّةِ‌ۖ قُلْ هِىَ مَوَٲقِيتُ لِلنَّاسِ وَٱلْحَجِّ‌ۗ وَلَيْسَ ٱلْبِرُّ بِأَن تَأْتُواْ ٱلْبُيُوتَ مِن ظُهُورِهَا وَلَـٰكِنَّ ٱلْبِرَّ مَنِ ٱتَّقَىٰ‌ۗ وَأْتُواْ ٱلْبُيُوتَ مِنْ أَبْوَٲبِهَا‌ۚ وَٱتَّقُواْ ٱللَّهَ لَعَلَّكُمْ تُفْلِحُونَ ١٨٩ They ask you ?O Prophet? about the phases of the moon. Say, “They are a means for people to determine time and pilgrimage.” Righteousness is not in entering your houses from the back doors. Rather, righteousness is to be mindful ?of Allah?. So enter your homes through their ?proper? doors, and be mindful of Allah so you may be successful.
