Surah 2. Al-Baqara
Ayah 189
189يَسْـَٔلُونَكَ عَنِ ٱلْأَهِلَّةِ ۖ قُلْ هِىَ مَوَٰقِيتُ لِلنَّاسِ وَٱلْحَجِّ ۗ وَلَيْسَ ٱلْبِرُّ بِأَن تَأْتُوا۟ ٱلْبُيُوتَ مِن ظُهُورِهَا وَلَـٰكِنَّ ٱلْبِرَّ مَنِ ٱتَّقَىٰ ۗ وَأْتُوا۟ ٱلْبُيُوتَ مِنْ أَبْوَٰبِهَا ۚ وَٱتَّقُوا۟ ٱللَّهَ لَعَلَّكُمْ تُفْلِحُونَ
[189] They ask you about the phases of the moan. Say, "These are signs for the people to reckon dates and fix the periods for hajj."198 Also tell them, "It is no virtue to enter your houses from their backs during the Hajj days); real virtue is that one should refrain from incurring the displeasure of Allah; so enter your houses by their proper doors. and fear Allah so that you may gain (true) success.199
198The phases of the moon have attracted the attention of mankind in every age, and different kinds of rites and superstitions have been connected with these in every country. The Arabs also had some superstitions connected with these. They took omens from them for journeys, marriage ceremonies, business, etc., and performed some superstitious practices, for they believed that the phases and the eclipse of the moon affected their fortunes. Therefore they questioned the Holy Prophet concerning this. Allah answered their question and informed them that the phases of the moon were nothing but uatural calendar in the sky to indicate dates of the month to the people simultaneously throughout the world. Hajj has been specially mentioned in this connection because of its religious, cultural and economic importance to the Arabs. Four months of the year were fixed for Hajj and 'Umrah during which war was suspended and the routes were made safe, and business flourished on account of peace.
199This was one of their superstitious customs. As soon as they put on the Ihram, the ceremonial dress for Hajj, they would not enter their houses by the front doors, but would enter them by jumping over the walls or through windows in the rear of their houses. In this verse, Allah has not only refuted this superstitious custom but also warned that virtue has nothing to do with the superstitious rites and customs which were being practised merely in blind imitation of their forefathers, for they did not affect the fortune of man in any way.
