Asalamualaikum.
Deobandis, and Barelwis quote a Hadith where the Prophet (SAW) requested his parents to come back to life, take the shahadah, and then they were laid to rest one more time.
Please quote the original source, and whether it is deemed authentic.
الجواب وبالله التوفيق
There is difference of opinion in this matter and it is very delicate too, therefore, it demands caution that one should keep silence in this matter. Moreover, neither this matter is related to Aqeedah(mandatory beliefs) nor it will be asked about in the grave or on the day of judgement. Therefore, to keep silence is better. The Ulama e Kiram say the same in this matter.
واللہاعلم بالصواب
