After graduating, Sheikh Ata Abu Rashta worked in a number of Arab countries as a civil engineer and wrote a book concerning the calculation of quantities in relation to the construction of buildings and roads.

Sheikh Ata Abu Rashta joined Hizb ut-Tahrir in the mid-1950s and subsequently carried out party activism throughout the Arab world. He worked closely with Sheikh Taqiuddin an-Nabhani, the founder of Hizb ut-Tahrir and Sheikh Abdul Qadeem Zallum who became the leader of Hizb ut-Tahrir following Sheikh Nabhani's death in 1977. In the 1980s he was a leading member of Hizb ut-Tahrir in Jordan and was appointed as Hizb ut-Tahrir's official spokesperson.Sheikh Ata Abu Rashta played a prominent role in Jordan during the Persian Gulf War when he convened press conferences, lectures and debates at public venues throughout the country.

He was regularly detained by the Jordanian authorities.In 1994, in an interview, Sheikh Ata Abu Rashta said, "The establishment of the Caliphate is now a general demand among Muslims, who yearn for this: the call for Islamic government (the Caliphate) is widespread in Egypt, Syria, Turkey, Pakistan, Algeria and so on. Before Hizb al-Tahrir launched its careeer the subject of the Caliphate was unheard of. However, the party has succeeded in establishing its intellectual leadership, and now everyone has confidence in its ideas, and talks about it: this is clear from the media worldwide".Abu Rashta became the global leader of Hizb ut-Tahrir on 13th April 2003 following the death of Sheikh Abdul Qadeem Zallum.Since assuming the leadership of Hizb ut-Tahrir, has spoken at conferences across the world including Indonesia, Pakistan and Yemen.

He is ever praying to Allah Almighty that He grant him the courage to discharge his duties in a manner that Allah (swt) and His Prophet (saw) would be pleased with; he is ever praying that Allah (swt) bestow upon the Ummah the state of Khilafah "Caliphate" through his hands; our Lord is All Hearing and will answer our prayers.

The steps taken by him during his time include the warm call made to Muslims on Rajab 28, 1426 Hijri corresponding to September 2, 2005 CE with relevance to the painful incident of abolition of Khilafah "Caliphate" 84 years ago. This appeal was initiated in Indonesia, and then it was made on the shores of Pacific Ocean in the East as well as on the shores of Atlantic Ocean in the West at the Friday prayers. This call affected the Ummah greatly. Additionally, he has been actively raising his voice for the Truth continuously at various conferences, seminars and conventions of Hizb ut Tahrir.

The early years of his leadership are full of khair and we pray to Allah (swt) that He may increase His barakah in his leadership. There are clear signs of imminent Nussrah under his leadership with the Will of Allah (swt). We look to him hopefully and we pray that Allah (swt) decrees His victory during his time, Ameen.

The piety of this exalted Ameer is exemplary. He is passionate about his mission and always concerned about fulfilling his obligations in a gracious manner. He has proved his capabilities while he held many offices in the administration of Hizb and fulfilled his obligations in the best possible manner. Some of the noteworthy services rendered by him include the ones that he did when held the offices of Representative, Mo'atamad and Assistant to the previous Ameer. This is the reason why he is fully aware of the responsibilities that he carries as the Ameer and perceives them rightly. He monitors all the activities actively, therefore, the Shabab feel his presence in everything that they do; no matter how small or huge the task. This is the way how he is utilizing the full potential of Shabab.
