Ghousul-Waqt, Abul-Fadl Shamshudeen, Sayyid Shah Ale'Ahmed Ach'che Mia (may Allah be pleased with him) was born on 28 Ramadaan 1160 Hijri in Mahrerah Shareef, India. He was the eldest son of Sayyid Shah Hamza Qadiri Barkati (may Allah be pleased with him). He is a direct descendent of Sayyiduna Rasoolullah (Allah bless him and give him peace).

Sayyid Shah Ale' Ahmed Ach'che Mia (may Allah be pleased with him) undertook his entire external Shariah and spiritual training under the guidance of Sayyid Shah Hamza Qadiri Barkati (may Allah be pleased with him). It is also mentioned by his family members that Sayyid Shah Ale'Ahmed Ach'che Mia (may Allah be pleased with him) resembled, physically that of Sayyiduna Abdul Qadir Jilani (may Allah be pleased with him).

He also studied Medicine (Hikmat) from the then celebrated Physician, Hakim Nasrullah. Hundreds of patients came to him to be cured. The medication was mostly leaves from ordinary trees. This simple medication used to cure any common or complicated sickness. Curing the sick was a special gift of Almighty Allah bestowed upon Him. This was one of his many Karamaat (Miracles).

He was a very devout Mystic and performed some of the most strenuous forms of devotion in the path of Suluk. He was a master of Habse Kabeer (to engross oneself so intensely in Zikrullah that the Saalik only breathes twice in 24 hours). He also regularly practiced Salaatul Makoos (to be hung upside down, tied with ropes to the feet and perform Salaah). He strictly performed all Sunnah and Nafil duties daily. From a young age of 10, he never missed his Tahajjud Salaah.

His biggest academic contribution was the compilation of a masterpiece, "Ah'een-e-Ahmadi", in 34 bulky volumes. The uniqueness of these volumes is that they consist of every science of knowledge known to man on earth. This alone will tell us of the depth of his comprehensive knowledge.

Many of his Karamaat are recorded. It is recorded in "Aa'thaar-e-Ahmedi" that once a young man came to Mahrerah Shareef from Bukhara (Russia) to visit Sayyid Ach'che Mia (may Allah be pleased with him). He first went to the Masjid and offered Zohr Salaah. Thereafter, he humbled himself at the feet of the Shaikh and said: "Your Holiness! I heard of you and traveled a long way to meet you. I am a very weak servant of Almighty Allah and do not possess the strength and courage to make strenuous Mujahidah (spiritual devotion). I have come to you for divine blessings so that I may achieve this enormous gift without any effort and struggle".

On hearing this, the Spiritual Master smiled and said: "You wish to achieve such great wealth in so little time". One of the disciples present, remarked: "Do you think that this is some type of sweet that can just be placed into the mouth and eaten!" The Murshid-e-Kaamil was displeased with this remark and reprimanded the disciple by saying: "Nothing is impossible in the Qudrat of Almighty Allah". He then taught the young man a specific Durood Shareef with necessary instructions and ordered him to recite it at night.

The same night the devotee obeyed all instructions and began the recital in seclusion. Suddenly, he experienced a state of spiritual enlightenment. He was blessed with the Ziyaarat of Sayyiduna Rasoolullah (Allah bless him and give him peace). This vision was not spiritual but physical. Early the next morning, he immediately went to the Murshid-e-Kaamil and cried: "Subhan-Allah! Last night I met Sayyiduna Rasoolullah (Allah bless him and give him peace) who said to me, 'In every century there will be a person in my Ummah who will revive my Deen'. Hence, O Master! Verily in this century, you are that eminent personality."

Just by the prescription of a single Durood Shareef and personally rendering his spiritual guidance, this grand master, in a short period of time without Mujahidah, led a disciple to spiritual perfection. It is said that Mujahidah is the most difficult science in the mystical path of Suluk. According to the exalted mystics, it takes a minimum of 80 consecutive years of absolute devotion to reach this stage. But here the blessings of this great Wali of Almighty Allah, condensed a long period of 80 years to less than 80 moments!

Ghousal-Waqt, Murshid-e-Kabeer (may Allah be pleased with him) was married and had one son and a daughter. The son, as ordained by Allah Subhaanahu Wa Ta'ala, passed away at a very young age. He was born a Wali and whatever he said became a reality. His daughter also passed away when she was an infant.

He had thousands of Mureeds and many Khulafa. There are also numerous devotees that lived at the Khanqah undertaking spiritual training of Suluk. He also cared for hundreds of poor and destitute. He adopted his nephew, Khatimul Akaabir Shah Ale' Rasool Ahmadi (may Allah be pleased with him) as his son. Sayyid Shah Ale'Ahmed Ach'che Mia was the fourth succeeding Qutb of the Barakatiyya Silsila and Sayyid Sha Ale'Rasool, his successor, was the fifth Qutbul-Waqt. Khatimul Akaabir was the Pir-O-Murshid of Alahazrat Imam Ahmad Raza Khan Qadiri (may Allah be pleased with him).

Sayyid Sha Ale'Ahmed Ach'che Mia Qadiri Barkati (may Allah be well pleased with him) peacefully left this mundane world at the age of 75 in the morning of 25 Rabbi-ul-Awwal Shareef 1235 Hijri.
