[20].Surah Taha [Tâ-Hâ]: Ayat 72-73

Ayat 72. They said: "We prefer you not over the clear signs that have come to us, and to Him (Allah) Who created us. So decree whatever you desire to decree, for you can only decree (regarding) this life of the world.

Ayat 73. "Verily! We have believed in our Lord, that He may forgive us our faults, and the magic to which you did compel us. And Allah is better as regards reward in comparison to your [Firaun's (Pharaoh)] reward, and more lasting (as regards punishment in comparison to your punishment)." 

[Tafseer] Clear Signs: the miracles, the personality of the Messengers of Allah, the logic of events as they unfolded themselves, and the light of inner conviction in their own conscience. There are, in addition, the Signs and Proofs of Allah in nature, which are referred to in many places, Thus was the first part of the mission of Moses—that to the Egyptians—fulfilled. The magic, mummery, and deceptions which pertained to Egyptian Pagan religion became a creed, a State article of faith, to which all citizens were compelled to bow, and to which its priests were compelled actively to practise. And Pharaoh was at the head of the whole system—the high priest or the supreme god. With justice, therefore, do the converted magicians lay the blame on Pharaoh, effectively negativing Pharaoh's disingenuous charge that they had been in league with Moses. These falsehoods and deceptions—combined in many cases with horrid cruelties, open and secret— we common to many Pagan systems.   

Hazrat Uthman bin `Affan (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said, "He who recites three times every morning and evening: `Bismillahil-ladhi la yadurru ma`as-mihi shai'un fil-ardi wa la fis-sama'i, wa Huwas-Sami`ul-`Alim (In the Name of Allah with Whose Name there is protection against every kind of harm in the earth or in the heaven, and He is the All-Hearing and All-Knowing),' nothing will harm him.''

[Abu Dawud Hadith # 5088 and At-Tirmidhi Hadith # 3388].

Lesson : as mentioned above in Surah Taha Ayat 73.""Verily! We have believed in our Lord, that He may forgive us our faults" The prayer cited in this Hadith means that "I seek the Protection of Allah by means of which one can save himself from every vice, whether it is an animal or man, a jinn or Satan because He is Aware of everyone's condition and Capable of hearing everybody's petition. He who comes in His Protection none can harm him, except that which He wills.''
