i've a better one right from Qur'aan...2 of them:
1. wasta'iino bis-sabi was-salaat = find peace thru prayer and patience
2. inna-Allaha ma'as-saabireen = Allah is with those who are steadfast
there's another one i always found peace in "Fa-inna ma'al usre yusra.Wa inna ma'al usre yusra"..(for sure there's ease after every hardship)
