[Machine] He buys it, then he goes to the Messenger of Allah ﷺ and consults him in that. The Messenger of Allah ﷺ tells him, "Do not count it as a charity."
أَنْ يَشْتَرِيَهُ ثُمَّ أَتَى رَسُولَ اللهِ ﷺ فَاسْتَأْمَرَهُ فِي ذَلِكَ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ «لَا تَعُدْ فِي صَدَقَتِكَ»
ʿUmar bin Al-Khattab gave a horse in charity in Allah's Cause and later he saw it being sold in the market and intended to purchase it. Then he went to the Prophet ﷺ and asked his permission. The Prophet said, "Do not take back what you have given in charity." For this reason, Ibn ʿUmar never purchased the things which he had given in charity, and in case he had purchased something (unknowingly) he would give it in charity again.
أَنْ يَشْتَرِيَهُ ثُمَّ أَتَى النَّبِيَّ ﷺ فَاسْتَأْمَرَهُ فَقَالَ لاَ تَعُدْ فِي صَدَقَتِكَ فَبِذَلِكَ كَانَ ابْنُ عُمَرَ ؓ لاَ يَتْرُكُ أَنْ يَبْتَاعَ شَيْئًا تَصَدَّقَ بِهِ إِلاَّ جَعَلَهُ صَدَقَةً
'Umar give a house in charity for the sake of Allah, the Mighty and Sublime, and he found it being offered for sale after that. He wanted to buy it, then he went to the Messenger of Allah and asked him about that. The Messenger of Allah said: "Do not take back what you have given in charity."
أَنَّ عُمَرَ تَصَدَّقَ بِفَرَسٍ فِي سَبِيلِ اللَّهِ ﷻ فَوَجَدَهَا تُبَاعُ بَعْدَ ذَلِكَ فَأَرَادَ أَنْ يَشْتَرِيَهُ ثُمَّ أَتَى رَسُولَ اللَّهِ ﷺ فَاسْتَأْمَرَهُ فِي ذَلِكَ فَقَالَ رَسُولُ اللَّهِ ﷺ لاَ تَعُدْ فِي صَدَقَتِكَ
