[Machine] The Messenger of Allah ﷺ prohibited two types of fasting, two types of prayers, two types of clothing, two types of eating, two types of marriage contracts, and two types of sales contracts. As for the two days, they are the day of Eid al-Fitr and the day of Eid al-Adha. As for the two prayers, they are the prayer after dawn until the sun rises, and the prayer after Asr until the sun sets. As for the two types of clothing, it is for a person to make himself modest in one garment without having anything between his private parts and the sky, and this is called "the lower garment". As for the two types of eating, it is for a person to eat with his right hand and drink with his left hand, and to eat while reclining. As for the two types of sales contracts, a man says to another man, "Sell to me and I will sell to you." As for the two types of marriage contracts, it is the marriage of adultery and the marriage of a man to his paternal or maternal aunt.  

نَهَى رَسُولُ اللهِ ﷺ عَنْ صَوْمَيْنِ وَعَنْ صَلَاتَيْنِ وَعَنْ لِبَاسَيْنِ وَعَنْ مَطْعَمَيْنِ وَعَنْ نِكَاحَيْنِ وَعَنْ بَيْعَتَيْنِ فَأَمَّا الْيَوْمَانِ فَيَوْمُ الْفِطْرِ وَيَوْمُ الْأَضْحَى وَأَمَّا الصَّلَاتَانِ فَصَلَاةٌ بَعْدَ الْغَدَاةِ حَتَّى تَطْلُعَ الشَّمْسُ وَصَلَاةٌ بَعْدَ الْعَصْرِ حَتَّى تَغْرُبَ الشَّمْسُ وَأَمَّا اللِّبَاسَانِ فَأنْ يَحْتَبِيَ فِي ثَوْبٍ وَاحِدٍ وَلَا يَكُونَ بَيْنَ عَوْرَتِهِ وَبَيْنَ السَّمَاءِ شَيْءٌ فَتُدْعَى تِلْكَ الصَّمَّاءَ وَأَمَّا الْمَطْعَمَانِ فَأَنْ يَأْكُلَ بِشِمَالِهِ وَيَمِينُهُ صَحِيحَةٌ وَيَأْكُلَ مُتَّكِئًا وَأَمَّا الْبَيْعَتَانِ فَيَقُولُ الرَّجُلُ تَبِيعُ لِي وَأَبِيعُ لَكَ وَأَمَّا النِّكَاحَانِ فَنِكَاحُ الْبَغِيِّ وَنِكَاحٌ عَلَى الْخَالَةِ وَالْعَمَّةِ
