The word(s) "formerly" appears 3 time(s) in 3 verse(s) in Quran in Muhammad Pickthal translation.

(1) The foolish of the people will say: What hath turned them from the qiblah which they formerly observed? Say: Unto Allah belong the East and the West. He guideth whom He will unto a straight path.

(2) Thus We have appointed you a middle nation, that ye may be witnesses against mankind, and that the messenger may be a witness against you. And We appointed the qiblah which ye formerly observed only that We might know him who followeth the messenger, from him who turneth on his heels. In truth it was a hard (test) save for those whom Allah guided. But it was not Allah's purpose that your faith should be in vain, for Allah is Full of Pity, Merciful toward mankind.

(3) Lo! religion with Allah (is) the Surrender (to His Will and Guidance). Those who (formerly) received the Scripture differed only after knowledge came unto them, through transgression among themselves. Whoso disbelieveth the revelations of Allah (will find that) lo! Allah is swift at reckoning.
