Hier ein Auszug zu den 9 Zeichen von Ibn Kathir rahimahullah.
Allah tells us that He sent Musa with nine clear signs, which provided definitive proof that his prophethood was real and that what he was conveying from the One Who had sent him to Fira`wn was true. These clear signs were: his staff, his hand, the years of famine, the sea, the flood, the locusts, the lice, the frogs and the blood. This was the view of Ibn `Abbas. Muhammad bin Ka`b said, "They were his hand and his staff, the five signs mentioned in Al-A`raf, and destruction of wealth and the rock.'' Ibn `Abbas, Mujahid, `Ikrimah, Ash-Sha`bi and Qatadah said: "They are his hand, his staff, the years of famine, the failure of the crops, the flood, the locusts, the lice, the frogs and the blood.''
