Musannaf Ibn Abi Shaybah 32382 — Book of Faith

Tariq bin Shihab al-Ahmasi (may Allah have mercy on him) said that Sayyiduna Salman (may Allah be pleased with him) said: "The example of the five prayers is that of shares of the spoils of war. Whoever takes five shares of it is better than one who takes four shares; whoever takes four shares is better than one who takes three; whoever takes three shares is better than one who takes two; and whoever takes two shares is better than one who takes a single share. And Allah has not made the one who has a share in Islam like the one who has no share."
