The ruling on a person who says

A: Firstly, Du`a' (supplication) of a Slave to Allah is permissible and commendable, and raising one's hands while adjuring and beseeching Him is also permissible. However, wiping them both over the face after supplicating Allah is only reported in a Da`if (weak) Hadith related by Ibn Majah on the authority of Salih ibn Hassan Al-Nadry on the authority of Muhammad ibn Ka`b Al-Qurazhy on the authority of Ibn `Abbas (may Allah be pleased with them) that the Prophet (peace be upon him) said, When you supplicate to Allah, do so with the face of your palms, not the backs. After you have finished, rub your face with them. Because of the ranking of Salih ibn Hassan as Da`if by Ahmad, Ibn Ma`in, Abu Hatim and Al-Daraqutny. Al-Bukhari said, "His Hadith is rejected." Abu Nu`aym Al-Asbahany said, "His Hadith is rejected and abandoned." (Part No. 6; Page No. 92)  Ibn Hibban said, "He used to listen to female signers and narrated many fabricated Hadith attributing them to trustworthy and reliable narrators." Ibn Al-Jawzy said regarding this Hadith, "It is not authentic due to the presence of Salih ibn Hassan in the chain of narration." Another Hadith has been reported concerning this matter related by Al-Tirmidhy in his Sunan. He said: Abu Musa Muhammad ibn Al-Muthanna and Ibrahim ibn Ya`qub and more than one person told us that Hammad ibn `Isa Al-Juhany told us on the authority of Hanzhalah ibn Abu Sufyan Al-Jumahy from Salim ibn `Abdullah from his father from `Umar ibn Al-Khattab (may Allah be pleased with him) that he said, Whenever Allah's Messenger (peace be upon him) raised his hands for Du`a' (supplication), he would not lower them until passing them over his face. Muhammad ibn Al-Muthanna said in his narration: "He would not lower them until passing them over his face." Abu `Isa said, "This is a Gharib authentic Hadith that we can only trace through Hammad ibn `Isa who narrated it solitarily; he was not a proliferate narrator. He also said that Handhalah ibn Abu Sufyan is Thiqah (trustworthy). He was regarded as such by Yahya ibn Sa`id Al-Qattan, but it has Hammad ibn `Isa who is a weak narrator and is the only reporter of the Hadith as mentioned by Al-Tirmidhy. Thus, Du`a' is a prescribed `Ibadah (worship); due to the absence of a Sunnah (whatever is reported from the Prophet), practical or verbal, and that the Hadith narrated in this regard is reported through weak narrations, it is better to abandon it in favor of the authentic and sound Hadith that made no mention of wiping both hands over the face. (Part No. 6; Page No. 93)  Secondly, the basic rule concerning all acts of worship is that they are Tawqifiy and that Allah can only be worshipped through what He has enjoined and prescribed. Furthermore, it has not been reported from the Prophet (peace be upon him) that upon hearing the Iqamah (call to start the Prayer) he said "May Allah establish it and cause it to continue." However, it is related by Abu Dawud in his Sunan in a weak narration that he said: Sulayman ibn Dawud Al-`Ataky told us that Muhammad ibn Thabit told us that a man from the people of the Levant (the region covering Syria, Lebanon, Jordan, and Palestine) told me on the authority of Shahr ibn Hawshab from Abu Umamah, or from some of the Sahabah of the Prophet (peace be upon him) that Bilal started giving Iqamah and when he said, "the time of Salah has come," the Prophet replied saying, "May Allah establish it and cause it to continue." The reason behind the weakness is that it has an unknown narrator, and in which case such a narrator is not considered reliable in his reporting. The above said, it becomes impermissible to say "May Allah establish it and cause it to continue" when the Mu'adhin says "the time of Salah has come" because nothing of the sort has been reported from the Prophet (peace be upon him). It is better to repeat the same words said in the Adhan, as the Prophet (peace be upon him) said, When you hear the Mu'adhin (caller to prayer), repeat what he says. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
