Invocation for At-Tashahhud (sitting in prayer)
 

"التَّحِيَّاتُ للهِ، وَالصَّلَوَاتُ، وَالطَّيِّبَاتُ، السَّلَامُ عَلَيْكَ أَيُّهَا النَّبِيُّ وَرَحْمَةُ اللهِ وَبَرَكَاتُهُ، السَّلَامُ عَلَيْنَا وَعَلَى عِبَادِ اللهِ الصَّالِحِينَ. أّشَْدُ أَنْ لَا إِلَهَ إِلَّا اللهُ وَأَشْهَدُ أَنَّ مُحَمَّداً عَبْدُهُ وَرَسُولُهُ".

52. Attahiyyaatu lillaahi wassalawaatu , wattayyibaatu , assalaamu 'alayka 'ayyuhan-Nabiyyu wa rahmatullaahi wa barakaatuhu, assalaamu 'alaynaa wa 'alaa 'ibaadillaahis-saaliheen. 'Ash-hadu 'an laa 'ilaaha 'illallaahu wa 'ash-hadu 'anna Muhammadan 'abduhu wa Rasooluhu.

All greetings of humility are for Allah , and all prayers and goodness . Peace be upon you , O Prophet , and the mercy of Allah and His blessings . Peace be upon us and upon the righteous slaves of Allah . I bear witness that there is none worthy of worship but Allah , and I bear witness that Muhammad is His slave and His Messenger.
