78th Ayah from Surah Al Hajj
Sahih International
And strive for Allah with the striving due to Him. He has chosen you and has not placed upon you in the religion any difficulty. [It is] the religion of your father, Abraham. Allah named you "Muslims" before [in former scriptures] and in this [revelation] that the Messenger may be a witness over you and you may be witnesses over the people. So establish prayer and give zakah and hold fast to Allah . He is your protector; and excellent is the protector, and excellent is the helper.
Abdul Haleem
Strive hard for God as is His due: He has chosen you and placed no hardship in your religion, the faith of your forefather Abraham. God has called you Muslims––both in the past and in this [message]––so that the Messenger can bear witness about you and so that you can bear witness about other people. So keep up the prayer, give the prescribed alms, and seek refuge in God: He is your protector––an excellent protector and an excellent helper.

And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of Islamic Monotheism to mankind by inviting them to His religion, Islam), and has not laid upon you in religion any hardship, it is the religion of your father Ibrahim (Abraham) (Islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Quran), that the Messenger (Muhammad SAW) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs] He is your Maula (Patron, Lord, etc.), what an Excellent Maula (Patron, Lord, etc.) and what an Excellent Helper!
Taqi Usmani
Struggle for (seeking the pleasure of) Allah, a struggle that is owed to Him. He has chosen you and did not impose any hardship on you in the religion, the faith of your father Ibrāhīm. He (Allah) named you as Muslims earlier and also in this (Qur’ān), so that the Messenger becomes a witness to you, and you become witnesses to (other) people. So establish Salāh, pay Zakāh and hold fast to Allah. He is your patron. So, how excellent He is as a patron, and how excellent as a supporter!

And strive for Allah with the endeavour which is His right. He hath chosen you and hath not laid upon you in religion any hardship; the faith of your father Abraham (is yours). He hath named you Muslims of old time and in this (Scripture), that the messenger may be a witness against you, and that ye may be witnesses against mankind. So establish worship, pay the poor-due, and hold fast to Allah. He is your Protecting friend. A blessed Patron and a blessed Helper!
Pickthall
And strive in His cause as ye ought to strive, (with sincerity and under discipline). He has chosen you, and has imposed no difficulties on you in religion; it is the cult of your father Abraham. It is He Who has named you Muslims, both before and in this (Revelation); that the Messenger may be a witness for you, and ye be witnesses for mankind! So establish regular Prayer, give regular Charity, and hold fast to Allah! He is your Protector - the Best to protect and the Best to help!
