If somebody allows another to do something
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ جَبَلَةَ، كُنَّا بِالْمَدِينَةِ فِي بَعْضِ أَهْلِ الْعِرَاقِ، فَأَصَابَنَا سَنَةٌ، فَكَانَ ابْنُ الزُّبَيْرِ يَرْزُقُنَا التَّمْرَ، فَكَانَ ابْنُ عُمَرَ ـ رضى الله عنهما ـ يَمُرُّ بِنَا فَيَقُولُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى عَنِ الإِقْرَانِ، إِلاَّ أَنْ يَسْتَأْذِنَ الرَّجُلُ مِنْكُمْ أَخَاهُ.
Narrated Jabala: "We were in Medina with some of the Iraqi people, and we were struck with famine and Ibn Az- Zubair used to give us dates. Ibn `Umar used to pass by and say, "The Prophet (ﷺ) forbade us to eat two dates at a time, unless one takes the permission of one's companions."
