I asked al-Qasim b. Muhammad about a man who has three dwellings and bequeathed one third of each dwelling. He said: All of that is combined into a single dwelling. Then he said: Aishah told me that the Messenger of Allah ﷺ said: “Whoever does a deed that is not in accordance with our command, it is rejected.”

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 ﷺ قَالَ: «مَنْ عَمِلَ عَمَلاً لَيْسَ عَلَيْهِ أَمْرُنَا فَهُوَ رَدٌّ».

[AI] The Prophet of Allah ﷺ said, "Whoever does an action that is not in accordance with our command, it is rejected."

قَالَ رَسُولُ اللهِ ﷺ مَنْ عَمِلَ عَمَلًا لَيْسَ عَلَيْهِ أَمْرُنَا فَهُوَ رَدٌّ

[AI] Al-Qasim takes you out and placed in one dwelling, and I heard Aisha say that the Messenger of Allah ﷺ said, "Whoever does an action that is not in accordance with our teachings, then it is rejected."

الْقَاسِمُ يُخْرَجُ ذَاكَ حَتَّى يُجْعَلَ فِي مَسْكَنٍ وَاحِدٍ وَقَدْ سَمِعْتُ عَائِشَةَ تَقُولُ قَالَ رَسُولُ اللهِ ﷺ مَنْ عَمِلَ عَمَلًا لَيْسَ عَلَيْهِ أَمْرُنَا فَهُوَ رَدٌّ

The Messenger of Allah ﷺ said: "Whoever innovates something in this matter of ours (i.e. Islam) that is not part of it, will have it rejected." (Using translation from Ibn Mājah 14)

قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ أَحْدَثَ فِي أَمْرِنَا هَذَا مَا لَيْسَ مِنْهُ فَهُوَ رَدٌّ»

"مَنْ عَمِلَ عَمَلًا لَيسَ عَلَيهِ أَمْرُنَا فَهُوَ رَدٌّ".
