Doing the dhikr of tasbih, tahmid plants the gardens of Jannah

The Messenger of Allah ﷺ said: “I met Ibrahim on the night of my Isrāʾ ˹and Miʿrāj˺, so he said: "O Muhammad, give my Salam to your Ummah, and inform them that Jannah has pure (rich) soil and delicious water, and that it is a flat treeless plain, and that its seeds are:

subḥān Allāh, wa-al-ḥamdu lillāh wa-lā ilāha illā Allāh wa-Allāhu akbar

(Perfection belongs to Allah, and all praise belongs to Allah, and there is no god ˹worthy of worship˺ other than Allah, and Allah is greater.)"  

قَالَ رَسُولُ اللَّهِ ﷺ لَقِيتُ إِبْرَاهِيمَ لَيْلَةَ أُسْرِيَ بِي فَقَالَ: «يَا مُحَمَّدُ، أَقْرِئْ أُمَّتَكَ مِنِّي السَّلاَمَ وَأَخْبِرْهُمْ أَنَّ الْجَنَّةَ طَيِّبَةُ التُّرْبَةِ عَذْبَةُ الْمَاءِ وَأَنَّهَا قِيعَانٌ: وَأَنَّ غِرَاسَهَا:

(سُبْحَانَ اللَّهِ) وَ(الْحَمْدُ لِلَّهِ) وَ(لاَ إِلَهَ إِلاَّ اللَّهُ) وَ(اللَّهُ أَكْبَرُ)۔»  

the Messenger of Allah ﷺ said to those sitting with him: “Is one of you incapable of attaining a thousand good deeds?” So a questioner among those seated with him asked him: “How can one of us earn a thousand good deeds?” He said: “(When) one of you recites a hundred Tasbīḥāt a thousand good deeds are written for him, and a thousand evil deeds are wiped away from him.”  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لِجُلَسَائِهِ أَيَعْجِزُ أَحَدُكُمْ أَنْ يَكْسِبَ أَلْفَ حَسَنَةٍ فَسَأَلَهُ سَائِلٌ مِنْ جُلَسَائِهِ كَيْفَ يَكْسِبُ أَحَدُنَا أَلْفَ حَسَنَةٍ قَالَ يُسَبِّحُ أَحَدُكُمْ مِائَةَ تَسْبِيحَةٍ تُكْتَبُ لَهُ أَلْفُ حَسَنَةٍ وَتُحَطُّ عَنْهُ أَلْفُ سَيِّئَةٍ قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
