Types of Bid`ahs

Q 2: Imam Al-Naysabury reported from Ibn `Abbas (may Allah be pleased with them) that the names of the People of the Cave are useful for treatment, escape from danger and fighting fire if they are written on a parchment then thrown in the middle of a fire. They are also useful in preventing a baby from crying too much, by placing it under the head of the baby in his cradle and so on.The names of the People of the Cave are Yemlekha, Sectlina, Methlina, Martush, Bartush, Shadhnoush, Kafhatus, and Qatmir. Is it true and permissible to carry the names of the People of the Cave?It is reported from `Aishah (may Allah be pleased with her) that she said that Allah's Messenger (peace be upon him) said: "Whoever writes these five verses that contain fifty Qaf (Qaf is an Arabic letter) then puts them in some water and drinks it, will have inside their body one thousand means of cure, one thousand remedies, one thousand parts of mercy, one thousand parts of kindness, one thousand parts of certainty, one thousand parts of strength, one thousand parts of light and all his diseases, grudges, miseries and troubles will come to an end''. It is reported from Salman Al-Farisy (may Allah be pleased with him) that he said, 'O Messenger of Allah, I have committed sins in the past and I am at the end of my life, so teach me something which if I recite, my lifespan will be longer, my sins will be forgiven and my wishes will be fulfilled. He (peace be upon him) taught him these five Ayahs (Qur'anic verses) and said, 'Whoever recites these five Ayahs (Part No. 2; Page No. 266) and carries a parchment with them written on it, his lifespan gets longer, his sins are forgiven and his wishes are fulfilled. These are four successive Ayahs (Qur'anic verse) of Surah Al-Baqarah, the last Ayah of Surah Al-Ma'idah and one Ayah of Surah Al-Ra`d. Is it permissible to write the Qur'an in segmented letters with a pure liquid by placing it upon the epileptic person till he is cured by Allah's Will?Allah (Exalted be He) blessed me with a talent, that is, sitting by an enchanted person and placing my right hand on his head and reciting the Ayahs of Ruqyah (reciting Qur'an and saying supplications over the sick seeking healing). After that he (the enchanted person) watches the spell affecting him on the wall in front of him as if he is watching TV. This happened three times. Is there any harm in that? It should be noted that I write "Allah" with saffron on a plate and wipe it up with water then make the enchanted person drink this water and another one which I pour on his head. Is there any harm in this?I have read a message written by our master `Aly (may Allah be pleased with him) which is dictated to him by the master of all humans, Muhammad (peace be upon him). Then he (peace be upon him) gave it to Abu Dujanah to place it in his house after he complained that his house was haunted. Is it permissible for us to write such a message following the example of Allah's Messenger (peace be upon him) and place it in the house that is haunted by evil spirits?
