As-Saffat 37:75
وَلَقَدْ نَادَىٰنَا نُوحٌ فَلَنِعْمَ ٱلْمُجِيبُونَ
Walaqad nadana noohunfalaniAAma almujeeboon
And Noah had certainly called Us, and [We are] the best of responders.
And NūH did call Us (for help after he was disappointed with his people), so (We accepted his prayer, as) We are the best to respond.
