Narrated `Abdullah bin Abi `Aufa: Allah's Apostle said, "Know that Paradise is under the shades of swords."

Narrated Salim Abu-An-Nadr: `Abdullah bin Abi `Aufa wrote and I read what he wrote that Allah's Apostle said, "When you face them ( i.e. your enemy) then be patient."

And then he got up among the people and said, "O people! Do not wish to face the enemy (in a battle) and ask Allah to save you (from calamities) but if you should face the enemy, then be patient and let it be known to you that Paradise is under the shades of swords." He then said,, "O Allah! The Revealer of the (Holy) Book, the Mover of the clouds, and Defeater of Al-Ahzab (i.e. the clans of infidels), defeat them infidels and bestow victory upon us."

Narrated Salim Abu An-Nadr: (the freed slave of 'Umar bin 'Ubaidullah) I was Umar's clerk. Once Abdullah bin Abi Aufa wrote a letter to 'Umar when he proceeded to Al-Haruriya. I read in it that Allah's Apostle in one of his military expeditions against the enemy, waited till the sun declined.

Narrated `Abdullah bin Abi `Aufa: Allah's Apostle said, "Do not long for meeting your enemy, and ask Allah for safety (from all sorts of evil)." (See Hadith No. 266, Vol. 4)
