Salaat Ul Fajr with the Wudhu of Salaat Ul ‘Isha for 40 years
It is mentioned in Akhbaar Ul Akhyaar and in Qalaaid Ul Jawahir:
Translation: Hadhrat Abul Fatah Haravi (May Allah shower His mercy on him) says: I remained with Hadhrat Ghouse-Ul-Azam (May Allah be well pleased with him) for 40 years and during this entire period, I always saw him offering Salaat Ul Fajr with the Wudhu of Salaat Ul ‘Isha. (Akhbaar Ul Akhyaar, Pg. No. 40, in Qalaaid Ul Jawahir, Pg. No. 76)
For 15 years, Hadhrat Ghouse-Ul-Azam (May Allah be well pleased with him) finished one complete recitation of the Holy Quran every night. (Akhbaar Ul Akhyaar, Pg. No. 40; Jame’ Karamaat Ul Auliya)
Hadhrat Ghouse-Ul-Azam (May Allah be well pleased with him) himself describes his striving and mortification in these words:
It is narrated on the authority of Hadhrat Shaykh Abu ‘Abdullah Najjaar (May Allah shower His mercy on him) that Hadhrat Ghouse-Ul-Azam (May Allah be well pleased with him) said: I have borne many difficulties, if the like of whom descend on a mountain, it will burst asunder. (Qalaaid Ul Jawahir, Pg. No. 10)
