A promise with a timescale attached
The verse does not say when. It says after.
لِيُنفِقْ ذُو سَعَةٍ مِّن سَعَتِهِۦ ۖ وَمَن قُدِرَ عَلَيْهِ رِزْقُهُۥ فَلْيُنفِقْ مِمَّآ ءَاتَىٰهُ ٱللَّهُ ۚ لَا يُكَلِّفُ ٱللَّهُ نَفْسًا إِلَّا مَآ ءَاتَىٰهَا ۚ سَيَجْعَلُ ٱللَّهُ بَعْدَ عُسْرٍ يُسْرًا
…sa-yajʿalu-llāhu baʿda ʿusrin yusrā.
“Let a man of wealth spend from his wealth, and he whose provision is restricted - let him spend from what Allāh has given him. Allāh does not charge a soul except [according to] what He has given it. Allāh will bring about, after hardship, ease [i.e., relief].”
