speech and communication

لَّا يَسْمَعُونَ فِيهَا لَغْوًا إِلَّا سَلَـٰمًا ۖ وَلَهُمْ رِزْقُهُمْ فِيهَا بُكْرَةً وَعَشِيًّا

They will not hear therein any ill speech - only [greetings of] peace - and they will have their provision therein, morning and afternoon.

وَٱحْلُلْ عُقْدَةً مِّن لِّسَانِى

And untie the knot from my tongue

فَقُولَا لَهُۥ قَوْلًا لَّيِّنًا لَّعَلَّهُۥ يَتَذَكَّرُ أَوْ يَخْشَىٰ

And speak to him with gentle speech that perhaps he may be reminded or fear [Allāh]."

عَلَّمَهُ ٱلْبَيَانَ

[And] taught him eloquence.
