Ibn Abbas (may Allah be pleased with them both) said: When the Messenger of Allah (peace and blessings be upon him) intended the expedition of Tabuk, he said to al-Jadd bin Qays: "Are you interested in the women of Banu al-Asfar (the Romans)?" He said: Give me leave and do not put me into temptation. So Allah, the Mighty and Majestic, revealed this verse: "And among them is he who says: Give me leave and do not put me into temptation" [Surah al-Tawbah: 49].
