﴿ سَلَٰمٌۭ قَوْلًۭا مِّن رَّبٍّۢ رَّحِيمٍۢ ﴾
“peace and fulfillment through the word of a Sustainer who dispenses all grace.”
“Peace!” salāmun is a subject — the word qawlan is its predicate that is peace by way of a word from a Lord Who is Merciful to them in other words He says to them ‘Peace be on you!’
