The Hadith: 'Anyone who misses some Salahs knowing not their number may offer an optional night Salah on the last Friday of Ramadan'
Q: It is reported from the Messenger of Allah (peace be upon him) that he said:
"Anyone who misses some Salahs (Prayers) knowing not their number
may pray four Rak`ahs (units of Prayer) with only one Tashahhud (a recitation in the sitting position in the second/ last unit of Prayer). They should recite in each Rak`ah Surah Al-Fatihah then Surah Al-Qadr and Surah Al-Kawthar fifteen times. They should say while making the intention for Salah, 'I intend to pray four Rak`ahs as a Kaffarah (expiation) for the Salahs that I missed.'"
said: "I heard the Messenger of Allah (peace be upon him) say, 'It is a Kaffarah for the missed Salahs of four hundred years.' Whereupon
(may Allah honor him) said, 'It is a Kaffarah for the missed Salahs of one thousand years.' He thus was asked, 'For whom will the extra number of Salahs be counted?' He (`Aly) said, 'For a person's parents, wife, children, relatives, and the inhabitants of their town.' When a person finishes offering such a Salah, they should send peace and blessings on the Prophet (peace be upon him) one hundred times in any form they like then they should make the following Du`a' (supplication) three times: 'O Allah, as my obedience does not benefit You in any way and my disobedience does not harm You in any way, accept from me what does not benefit You in any way and forgive for me what does not harm You in any way. O Allah, you are the One Who fulfills His Promises and forgives people who have wronged themselves. Forgive thus (Part No. 3; Page No. 210) Your slave who wronged themselves. I seek refuge with You from the vanity of wealth and the hardship of poverty. O Allah, You created me after I had been nothing. You gave me provision after I had owned nothing. Then I committed sins. I acknowledge all my bad deeds. If You forgive me, Your Kingdom will not decrease in any way. If You punish me, Your Kingdom will not increase in any way. O Allah, You can find other people than me to punish but I cannot find any one other than You to be merciful to me. O Most Merciful One, forgive for me what is between me and You and forgive for me what is between me and people. O Hope of the supplicant and Security for the scared! Grant me Your great Mercy. You are the Most Merciful, O Lord of the whole universe. O Allah, forgive the believing men and women and the Muslim men and women and help us to extend their good deeds. O my Lord, forgive me and bestow on me Your Mercy for You are the Best of those who show mercy. May Peace and Blessings of Allah be upon Prophet Muhammad, his family, and Companions.'"
The above Hadith is false and fabricated. It is not mentioned in any of the recognized books of Hadith. Moreover, it is well established that anyone who misses a Salah has to hasten to make it up once they remember it. This is because it is authentically reported that the Prophet (peace be upon him) said:
Anyone who misses a Salah because they sleep or forget it, they have to offer it when they remember it. There is no Kaffarah for it except this.
As for the Salah mentioned in the question in which Surahs Al-Qadr and Al-Kawthar are to be repeated fifteen times, it is a Bid`ah (innovation in religion) Salah that opposes the ordained Salah. (Part No. 3; Page No. 211) Moreover, the Du`a' to be read after the Salah mentioned in the question comprises some unsuitable phrases, such as "O Allah, You can find other people than me to punish" and "O Security of the scared!" Consequently, offering such a Salah is not permissible, for it is a fabricated Salah.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
