Translation of the verse 75 from Surah As-saffat : Number of verses 182 - - page 448 - Part 23.
And indeed Nuh (Noah) invoked Us, and We are the Best of those who answer (the request).
And Noah had certainly called Us, and [We are] the best of responders.
(37:75) Noah *39 had called upon Us (earlier). *40 See, how excellent We were in answering him!
*39) This theme is related with the preceding sentences. A study of them shows why these stories are being narrated here.
*40) This refers to the prayer that the Prophet Noah had at last made to Allah Almighty, being disappointed with his people, after having preached the true Faith to them for a very long period of time, without much success. This prayer has been related in Surah All-Qamar, thus: "He called out to his Lord, saying: I am overcome: take now Thy vengeance." (v. 10).
