109: The Disbelievers ( Al Kafirun)

Some of the Meccan idolaters suggested to the Prophet  as a compromise that he should worship their gods for a year and they should worship his for a year. This was the reply. 

In the name of God, the Lord of Mercy, the Giver of Mercy

1 Say (Prophet), 'Disbelievers: 2 I do not worship what you worship, 3 you do not worship what I worship, 4 I will never worship what you worship, 5 you will never worship what I worship: 6 you have your religion and I have mine. ' 

110: Help (Al Nasr)

A Medinan surah said to be one of the last revelations the Prophet received before his death. 

In the name of God, the Lord of Mercy, the Giver of Mercy

1 When God's help comes and He opens up your way (Prophet), 2 when you see people embracing God's faith in crowds, 3 celebrate the praise of your Lord and ask his forgiveness: He is always ready to accept repentance.

111: Palm fibre (Al Masad)

This sura refers to the uncle of the Prophet who opposed him fiercely as did his wife. He insulted the Prophet with 'Tabak yadak' (may your hands be ruined). This Meccan sura is a retort.

In the Name of God, the Lord of Mercy, the Giver of Mercy

1 May the hands of Abu Lahab be ruined! May he be ruined too! 2 Neither his wealth nor his gains will help him: 3 he will burn in the Flaming Fire- 4 and so will his wife, the firewood carrier, 5 with a palm fibre rope around her neck.
