Recite this and it will suffice you in every way

The Messenger of Allah S.A.W.S said,
"Recite Surat Al-Ikhlas and Al-Mu`awwidhatain (Surat Al-Falaq and Surat An-Nas) three times at dawn and dusk. It will suffice you in all respects.''
[Abu Dawud and At-Tirmidhi]

Commentary: This means that then one would not need any other recitation for the remembrance of Allah. Moreover, by virtue of these three Surah, Allah will protect the reciter from every dangerous thing. In other Ahadith, it is stated that after lying in the bed, the Prophet (SAWS) used to recite these Surah, then blow on his hands and rub them over his body to the extent he could.

None of you should say "My soul has become evil"

Allah's Messenger (may peace and blessings be upon him) said: None of you should say: "My soul has become evil" but he should say: "My soul has become remorseless."

[Sahih Muslim]

"Qur'an escapes from memory faster than a camel from its ropes"

The Prophet S.A.W.S said,

"Read the Qur'an regularly. By the One in Whose Hand Muhammad's soul is, it escapes from memory faster than a camel does from its tying ropes.''
[Al-Bukhari and Muslim]

Commentary: To safeguard the Qur'an means to recite it regularly, because if one fails to do so, he tends to forget it quickly. In the absence of regular recitation, one is bound to forget it more quickly than a camel breaks loose bound with. The breaking loose by the camel to liberate itself is a simile for the quick process of forgetting.
