Don't be Sad
Verily, in the remembrance of Allah do hearts find rest
(Verily, in the remembrance of Allah do hearts find rest.)
(Qur'an 13: 28)
Truthfulness is beloved by Allah and is purifying soap for the heart. And there is no deed that gives such pleasure to the heart, or has greater reward, than the remembrance of Allah.
(Therefore remember me, and I will remember you…)(Qur'an 2: 152)
Remembrance of Allah is His paradise on earth, and whoever does not enter it will not enter the Paradise of the Hereafter. Remembrance is not only a safe haven from the problems and worries of this world, but it is also the short and easy path to achieving ultimate success. Read the various revealed texts that refer to the remembrance of Allah, and you will appreciate its benefits.
When you remember Allah, clouds of worry and fear are driven away, and the mountains that make up your problems are blown away.
We should not be surprised when we hear that people who remember Allah are at peace. What is truly surprising is how the negligent and unmindful survive without remembering Him.
)[They are] dead, lifeless, and they know not when they will be raised up.) (Qur'an 16: 21)
O' whosoever complains of sleepless nights and is in shock over his misfortune, call out His Holy Name.
(Do you know of any that is similar to Him! [There is nothing like unto Him and He is the All-Hearer; the All-Seer])
(Qur'an 19: 65)
To the degree that you remember Allah, your heart will be calm and cheerful. His remembrance carries with it the meaning of total dependence upon Him, of turning to Him for aid, of having good thoughts about Him, and of waiting for victory from Him. Truly, He is near when supplicated: He hears when He is called and He answers when He is invoked, so humble yourself before Him and ask of Him sincerely. Repeat His beautiful blessed name, and mention Him as being alone worthy of worship. Mention His praises, supplicate to Him, and ask forgiveness from Him: you will then find - by the will of Allah- happiness, peace, and illumination.
(So Allah gave them the reward of this world and the excellent reward of the Hereafter) (Quran 3: 148)
