Sa'd b. Ibrahim reported: I asked Qasim b. Muhammad about a person who had three dwelling houses and he willed away the third part of every one of these houses; he (Qasim b. Muhammad) said: All of them could be combined in one house; and then said: 'A'isha informed me that Allah's Messenger (ﷺ) said: He who did any act for which there is no sanction from our behalf, that is to be rejected.

وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَعَبْدُ بْنُ حُمَيْدٍ، جَمِيعًا عَنْ أَبِي عَامِرٍ، قَالَ عَبْدٌ حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عَمْرٍو، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ جَعْفَرٍ الزُّهْرِيُّ، عَنْ سَعْدِ بْنِ إِبْرَاهِيمَ، قَالَ سَأَلْتُ الْقَاسِمَ بْنَ مُحَمَّدٍ عَنْ رَجُلٍ، لَهُ ثَلاَثَةُ مَسَاكِنَ فَأَوْصَى بِثُلُثِ كُلِّ مَسْكَنٍ مِنْهَا قَالَ يُجْمَعُ ذَلِكَ كُلُّهُ فِي مَسْكَنٍ وَاحِدٍ ثُمَّ قَالَ أَخْبَرَتْنِي عَائِشَةُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَنْ عَمِلَ عَمَلاً لَيْسَ عَلَيْهِ أَمْرُنَا فَهُوَ رَدٌّ ‏"‏ ‏.‏
