For everything you lose

Which Ayah in Allah's Book is the greatest

السلام عليكم و رحمة الله و بركاته بِسْمِ اللهِ الرَّحْمنِ الرَّحِيمِThe Messenger of Allah (صلى الله عليه و سلم ) said: "Abu Mundhir! Do you know which Ayah in Allah's Book is the greatest?" I replied: " It is Allah la ilaha illa Huwal-Haiyul-Qayum (Allah! none has the right to be worshiped but He, the Ever Living..." (2:256) Thereupon he (صلى الله عليه و سلم ) patted me in the chest and said, "Rejoice by this knowledge, O Abu Mundhir!"[Muslim]
Commentary: The words cited in the Hadith occur in the beginning of Ayat-ul-Kursi (No.256 of Surat Al-Baqarah of the holy Qur'an)

Al-Mu'awwidhatain

السلام عليكم و رحمة الله و بركاته بِسْمِ اللهِ الرَّحْمنِ الرَّحِيمِThe Messenger of Allah (صلى الله عليه و سلم ) used to seek protection against the evil of jinn and the evil eyes till Surat Al-Falaq and Surat An-Nas were revealed. After the were revealed, he took to them for seeking Allah's protection and left everything else besides them.[At-Tirmidi]
Commentary: These Surah are also called 'Al-Mu'awwidhatain' which mean two Surah which provide protection. It is, therefore very useful to seek the protection of Allah by reciting them.

Read the Qur'an in a nice voice

السلام عليكم و رحمة الله و بركاته بِسْمِ اللهِ الرَّحْمنِ الرَّحِيمِ"He who does not read the Qur'an in a pleasant tone is not of us"[Abu Dawud]
Commentary: The words "is not of us" mean that he is not following the way of the Prophet (صلى الله عليه و سلم )with regard to recitation of the Qur'an.

Read Quran Often

السلام عليكم و رحمة الله و بركاته بِسْمِ اللهِ الرَّحْمنِ الرَّحِيمِ"Read the Qur'an regularly. By the One in Whose Hand Muhammad's (صلى الله عليه و سلم ) soul is, it escapes from memory faster than a came does from its tying ropes."[Al-Bukhari and Muslim]
