la tahzan

"Be not sad, surely Allah is with us."

(Qur'an 9:40)

"So do not lose heart, and do not fall into despair; for you must gain mastery if you are true in faith." 

(Qur'an 3:139)

Dan janganlah kamu (merasa) lemah, dan jangan pula bersedih hati, sebab kamu paling tinggi (darjatnya), jika kamu orang beriman.
