The Virtues of La ilaha illalahu wahdahu la shareeka lahu | Dr. Omar Suleiman 

لَا إِلهَ إِلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ، اللَّهُمَّ لَا مَانِعَ لِمَا أَعْطَيْتَ، وَلَا مُعْطِيَ لِمَا مَنَعْتَ، وَلَا يَنْفَعُ ذَا الْجَدِّ مِنْكَ الْجَدُّ

None has the right to be worshipped but Allah alone, He has no partner, His is the dominion and His is the praise, and He is Able to do all things. O Allah, there is none who can withhold what You give, and none may give what You have withheld; and the might of the mighty person cannot benefit him against You. Al-Bukhari 1/255, Muslim 1/414.
