وَلَسَوْفَ يُعْطِيكَ رَبُّكَ فَتَرْضَىٰ
“And [surely] your Lord will give so much to you that you will be pleased.”
This ayah is part of Surah al-Duha, revealed -- as this event's own description states -- to reassure the Prophet ﷺ that his Lord had not abandoned him after a woman of the Quraysh mocked the pause in revelation.
