Musannaf Ibn Abi Shaybah 7800 — The ruler who delays the prayer beyond

Sayyiduna Abdullah (bin Mas'ud) (may Allah be pleased with him) said: Soon there will be rulers over you who will delay the prayers beyond their times and squeeze them until the last gasp of the dying (the sun's final light). When you see them doing that, pray in your homes, and then pray with them with the intention of a voluntary prayer.
