وَالْحَوْضُ الَّذِي أَكْرَمَهُ اللَّهُ تَعَالَى بِهِ غِيَاثًا لِأُمَّتِهِ حَقٌّ
The Reservoir with which Allah honors His Prophet ﷺ as relief for his community is real.
إِنَّكَ لَا تَدْرِي مَا أَحْدَثُوا بَعْدَكَ
You do not know what they introduced after you.
How the passages fit: The Prophet’s ﷺ Reservoir is a special honor and a promise of relief for his community, accompanied by a warning about later religious innovations.
Application: Hope in the Reservoir is not a substitute for following the Sunnah. One should avoid inventing required beliefs or worship practices and treating them as transmitted religion.
Limit of inference: The warning about certain people does not permit unverified judgments on every named individual’s final fate.
