عَنْ حُذَيْفَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ مَنْ شَرَطَ لِأَخِيهِ شَرْطًا لَا يُرِيدُ أَنْ يَفِيَ لَهُ بِهِ فَهُوَ كَالْمُدْلِي جَارَهُ إِلَى غَيْرِ مَنَعَةٍ
It is narrated from Sayyiduna Hudhayfah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) said: Whoever makes a condition with his brother, while he does not intend to fulfill it, is like a man who hands over his brother to such a neighboring (nation) who have no power (to protect themselves from the enemy).
