Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "On the night I was taken on the Mi'raj, I met Ibrahim (peace be upon him). He said: O Muhammad! Convey my greetings to your Ummah and inform them that the soil of Paradise is pure and excellent, its water is sweet, and it is a flat plain, and saying «سبحان اللہ», «الحمد للہ», «لا إلہ إلا اللہ», «اللہ أکبر», and «لاحول ولا قوة الا بالله» is planting trees there."
