This hadith was narrated by Abu Hurairah and it talks about the importance of planting words from Allah in our hearts. The Prophet Muhammad ﷺ passed by him when he was planting a plant and asked him what he was doing. When Abu Hurairah told him that he was planting a plant for himself, the Prophet ﷺ asked if he would like to know about something better than that. He said yes and then the Prophet ﷺ told him to say "Subhan-Allah, wal-hamdu-lillah, wa la ilaha illallah, wa Allahu Akbar" which translates to "Glory is to Allah; praise is to Allah; none has the right to be worshiped but Allah; and God is Most Great". For each one of these phrases said with sincerity and faithfulness will result in a tree being planted for you in Paradise. This hadith teaches us how important it is for us as Muslims to remember our Lord through His words as this will bring us closer to Him and reward us with eternal bliss in Paradise.
