This article provides full translation and tafsir of Surah Quraysh, along with Arabic text.
Translation and Tafsir of Surah Quraysh
First up, the full Arabic text of Surah Quraysh:
- For the protection of the Quraysh
- Their protection during their trading caravans in the winter and the summer
- So let them worship the Lord of this House,
- Who has fed them against hunger and has made them safe from fear.
And now, on to the Tafsir of Surah Quraysh.
1. For the protection of the Quraysh
As the custodians of the Ka’bah, the “protection of the Quraysh” is equivalent to the security of the Ka’bah, for the sake of which the army of Abrahah was destroyed. In this verse, Allah Himself is taking the responsibility for the protection of Quraysh.
As in Surah al-Ankabut, regarding the safety of House of Allah, Allah says: 
Do they not then see that We have made a sanctuary secure, and that men are being snatched away from all around them?
2. Their protection during their trading caravans in the winter and the summer
For trade purposes, the Quraysh took caravans of merchandise to the warmer climate of Yemen in the winter and to the cooler climate of the Syrian summer, upon which the prosperity of Mecca depended. They were thus exposed to the dangers of hunger and robbery on the way. Thus, in this verse, Allah is reassuring their security.
3. So let them worship the Lord of this House,
After describing His Favours in first two verses of the Surah, Allah directs the Quraysh to worship Him, as He is the “Lord of the House” — Ka’bah.
4. Who has fed them against hunger and has made them safe from fear.
Again, in this last verse of the Surah, Allah is reminding people of His Favours upon them. Connecting this verse with the previous one, Allah says that they should worship Him Alone because He is the One Who guards them against hunger and keeps them safe from fear.
When Prophet Abraham (PBUH) completed the construction of the Ka’bah, he turned to Allah with the following prayer: 
And remember Abraham said: “My Lord, make this a City of Peace, and feed its people with fruits.”
And Allah answered his prayer, and helped the people of Mecca prosper and live in safety.
