It is narrated from Abu Salih and Ikrimah (may Allah have mercy on them both) concerning the saying of Allah, the Mighty and Majestic: "And We certainly gave Musa nine clear signs" [Surah al-Isra': 101], that they said: "What is meant by these nine signs is the years of famine in which rain was withheld from them, the decrease in the yield of fruits, the flood, the locusts, the lice, the frogs, the blood, the staff of Musa (peace be upon him) and his shining hand."
Imam Ahmad bin Mani' narrated this report in his Musnad.
