Indeed, in the creation of the heavens and the earth, and the alternation of the night and the day, and the [great] ships which sail through the sea with that which benefits people, and what Allāh has sent down from the heavens of rain, giving life thereby to the earth after its lifelessness and dispersing therein every [kind of] moving creature, and [His] directing of the winds and the clouds controlled between the heaven and earth are signs for a people who use reason.
In the creation of the heavens and earth, the alternation of night and day, are signs for those who think.
Wa-lladhi nafsi bi-yadih, la tadkhuluna-l-jannata hatta tu'minu, wa la tu'minu hatta tahabbu, awa la adullukum ala shay'in idha fa'altumuhu tahababtum? Afshu-s-salama baynakum.
By the One in whose hand is my soul, you will not enter Paradise until you believe, and you will not believe until you love one another. Shall I not guide you to something that, if you do it, you will love one another? Spread salam among yourselves.
