The word(s) "persevere" appears 25 time(s) in 25 verse(s) in Quran in Abdullah Yusuf Ali translation.

(21) Patiently, then, persevere: for the Promise of Allah is true: and ask forgiveness for thy fault, and celebrate the Praises of thy Lord in the evening and in the morning.

(22) So persevere in patience; for the Promise of Allah is true: and whether We show thee (in this life) some part of what We promise them,- or We take thy soul (to Our Mercy) (before that),-(in any case) it is to Us that they shall (all) return.

(23) If it be His Will He can still the Wind: then would they become motionless on the back of the (ocean). Verily in this are Signs for everyone who patiently perseveres and is grateful.

(24) Therefore patiently persevere, as did (all) messengers of inflexible purpose; and be in no haste about the (Unbelievers). On the Day that they see the (Punishment) promised them, (it will be) as if they had not tarried more than an hour in a single day. (Thine but) to proclaim the Message: but shall any be destroyed except those who transgress?

(25) And We shall try you until We test those among you who strive their utmost and persevere in patience; and We shall try your reported (mettle).
