So We responded to him, and We gave to him John, and amended for him his wife. Indeed, they used to hasten to good deeds and supplicate Us in hope and fear, and they were to Us humbly submissive.
So We answered him, and bestowed on him John, and We set his wife right for him; truly they vied with one another, hastening to good works, and called upon Us out of yearning and awe; and they were humble to Us.
So We listened to him: and We granted him Yahya: We cured his wife's (Barrenness) for him. These (three) were ever quick in emulation in good works; they used to call on Us with love and reverence, and humble themselves before Us.
يَدْعُونَنَا رَغَبًا وَرَهَبًا (and call Us with hope and fear - 21:90). This may be interpreted to mean that they call Allah Ta` ala both in comfort and distress. The other explanation of the verse is that during their prayers they remain suspended between hope and fear hoping that Allah would forgive their sins and fearing that their lapses may bring on them His displeasure.
