Aslim Taslam

Aslim Taslam (أسلم تسلم) is a phrase meaning "submit (to God, i.e., by accepting Islam) and you will get salvation", taken from the letters sent by the Islamic prophet Muhammad to various rulers in which he urged them to convert to Islam.

Letters of Muhammad
Muhammad, according to the usually told Islamic historiography, sent ambassadors with such letters to Heraclius the emperor of Eastern Roman Empire, Chosroes II the emperor of Persia, the Negus of Ethiopia, Muqawqis the ruler of Egypt, Harith Gassani the governor of Syria and Munzir ibn Sawa the ruler of Bahrain.

Muhammad's Letter to the King of Oman, Jaifer, and his Brother Abd Al-Jalandi -

In the Name of Allah, the Most Beneficent, the Most Merciful:

From Muhammad bin ‘Abdullah to Jaifer and ‘Abd Al-Jalandi - Peace be upon him who follows true guidance; thereafter I invite both of you to the Call of Islam. Embrace Islam. Allah has sent me as a Prophet to all His creatures in order that I may instill fear of Allah in the hearts of His disobedient creatures so that there may be left no excuse for those who deny Allah. If you two accept Islam, you will remain in command of your country; but if you refuse my Call, then all your possessions are perishable. My horsemen will appropriate your land, and my Prophethood will assume control over your kingship.

The account as transmitted by Muslim historians of the letter to Heraclius reads as follows

Western Translation
In the name of Allah the Beneficent, the Merciful: (This letter is) from Muhammad the slave of Allah and His Apostle to Heraclius the ruler of Byzantine. Peace be upon him, who follows the right path. Furthermore I invite you to Islam, and if you become a Muslim you will be safe, and Allah will double your reward, and if you reject this invitation of Islam you will be committing a sin by misguiding your Arisiyin (peasants). (And I recite to you Allah's Statement:) Say (O Muhammad): 'O people of the scripture! Come to a word common to you and us that we worship none but Allah and that we associate nothing in worship with Him, and that none of us shall take others as Lords beside Allah.' Then, if they turn away, say: 'Bear witness that we are Muslims' (those who have surrendered to Allah)."

Arabic original
بسم الله الرحمن الرحيم من محمد بن عبد الله إلى هرقل عظيم الروم: سلام على من اتبع الهدى، أما بعد فإنى أدعوك بدعوة الإسلام أسلم تسلم يؤتك الله أجرك مرتين، فإن توليت فعليك إثم جميع الأريسيِين قُلْ يَا أَهْلَ الْكِتَابِ تَعَالَوْا إِلَىٰ كَلِمَةٍ سَوَاءٍ بَيْنَنَا وَبَيْنَكُمْ أَلَّا نَعْبُدَ إِلَّا اللَّهَ وَلَا نُشْرِكَ بِهِ شَيْئًا وَلَا يَتَّخِذَ بَعْضُنَا بَعْضًا أَرْبَابًا مِّن دُونِ اللَّهِ ۚ فَإِن تَوَلَّوْا فَقُولُوا اشْهَدُوا بِأَنَّا مُسْلِمُونَ

In the name of God the Beneficent, the Merciful: (This letter is) from Muhammad son of Abdullah to Heraclius the Great (ruler) of the Romans (Byzantines). Peace be upon him, he who follows the right path. Furthermore I invite thee to Islam; become a Muslim and thou shalt be safe (from Hell or God's punishment), and God will double thy reward (as your people will follow along and be saved because of you), and if thou rejectest, thou shalt bear the sins of the Arisiyins (the peasants, your people).

(And I recite to you God's Statement:) Say (O Muhammad): 'O people of the scripture! Come to a word common to you and us that we worship none but God and that we associate nothing in worship with Him, and that none of us shall take others as Lords beside God. Then, if they turn away, say: 'Bear witness that we are Muslims' (those who have surrendered to God).
