Due to excess of fasts his back got bent

Sayyiduna ‘Isa Bin Zaazaan Ubulli رَحْمَةُ اللهِ تَعَالٰی عَلَيْه used to observe fasts abundantly due to which his back became bent and he رَحْمَةُ اللهِ تَعَالٰی عَلَيْه lost his voice.

Dear Islamic brothers! You have just heard how enthusiastic our pious saints رَحِمَهُمُ الـلّٰـهُ تَـعَالٰی had been that they observed fasts for 40 years, 60 years, or rather some observed fasts throughout their lives. The state of their sincerity was that they did not use to inform their family members about their fasts. Therefore, we should also observe the Nafl fasts of Rajab-ul-Murajjab, Sha’ban-ul-Mu’azzam, Shash Eid (six fasts after Eid-ul-Fitr), Monday, Thursday and days of Bayd (i.e. 13, 14, 15 of the Madani month) etc. in addition to the mandatory fasts of blessed Ramadan as Nafl fasts also have lots of excellences.

The Prophet of Rahmah, the Intercessor of the Ummah صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has stated: If someone observes a Nafl fast and (even if he) is given the whole earth full of gold (as a reward) his reward will still remain incomplete, he will be given his reward on the Day of Judgement only.

(Musnad Abi Ya’la, vol. 5, pp. 353, Hadees 6104)

Dear Islamic brothers! Ameer-e-Ahl-e-Sunnat ‘Allamah Maulana Abu Bilal Muhammad Ilyas Attar Qadiri Razavi Ziyaee دَامَـتْ بَـرَكَـاتُـهُـمُ الْـعَـالِـيَـه also loves Nafl fasts. That’s why he observes fasts very often except the days of the year in which a fast is prohibited. In addition to this, he دَامَـتْ بَـرَكَـاتُـهُـمُ الْـعَـالِـيَـه not only observes fasts throughout the month of Rajab-ul-Murajjab and other sacred months along with the fast of every blessed Monday, but also persuades other Islamic brothers to do so. By virtue of his persuasion many Islamic brothers and Islamic sisters are privileged either to observe the fasts of the whole Rajab-ul-Murajjab, or they observe fasts most of the days of Rajab-ul-Murajjab. Furthermore, there is a large number of those Islamic brothers who also fast on the blessed Monday.
