[18].Surah Al-Kahf [The Cave]: Ayat 16

Ayat 16. (The young men said to one another): "And when you withdraw from them, and that which they worship, except Allah, then seek refuge in the Cave, your Lord will open a way for you from His Mercy and will make easy for you your affair (i.e. will give you what you will need of provision, dwelling, etc.)."

[Tafseer] That is, 'do not be afraid of anything; put your whole case in the hands of Allah; at present you are being persecuted; he will solve your difficulties and give you ease and comfort'. The public protest ends at verse 15. In verse 16 they are taking counsel among themselves. After they go into the Cave.   

Hazrat Anas (May Allah be pleased with him) reported: The supplication most often recited by The Messenger of Allah [SAWW](PBUH) was: "Allahumma atina fid-dunya hasanatan, wa fil-akhirati hasanatan, wa qina `adhab-annar (O our Rubb! give us in this world that which is good and in the Hereafter that which is good, and save us from the punishment of the Fire).'''

[Al-Bukhari Book 35, Chapter 09, Hadith # 6507]. 

Lesson : as mentioned above in Surah Al-Kahf Ayat 16. "your Lord will open a way for you from His Mercy and will make easy for you your affair" It is desirable to recite this Du`a which is mentioned in the Qur'an (2:201) and which comprehends all that is good both in this life and the Hereafter. The Messenger of Allah [SAWW](PBUH) made it a habit to recite this Du`a, and the Companions were eager to follow him in all his words and actions.
