Musannaf Ibn Abi Shaybah

Hazrat Jabir Ra’ini, may Allah have mercy on him, narrates that when Hazrat Abu Bakr, may Allah be pleased with him, was bidding farewell to an army, he walked along with them and said: “All praise is for Allah, our feet have become dusty in His path.” A man said, “We have merely followed behind them.” Hazrat Abu Bakr, may Allah be pleased with him, said, “We prepared them, we walked behind them, and we prayed for them.”
