What is the ruling on one who says “When will the time for iftaar come?”?

The time of iftaar is the
time when the fast ends, which is the time of Maghrib prayer. There is no
sin on the one who asks about the time of iftaar so that he may enjoy the
things that Allaah has permitted to him of food, drink and intercourse, and
to feel the joy of having completed his worship. It was narrated that Abu
Hurayrah (may Allaah be pleased with him) said: The Messenger of Allaah
(peace and blessings of Allaah be upon him) said: “The fasting person has
two moments of joy: when he breaks his fast he rejoices at breaking his
fast, and when he meets his Lord he will rejoice at his fasting.” Narrated
by al-Bukhaari, 1805; Muslim, 1151. 

Al-Haafiz ibn Hajar (may Allaah have mercy on him) said: 

Al-Qurtubi said: What this means is that he rejoices at the
disappearance of his hunger and thirst when it becomes permissible for him
to break his fast. This joy is something natural and this is the first
meaning that comes to mind. And it was said that his joy when breaking the
fast is because he has completed his fast and finished his act of worship,
and his Lord is allowing him now to eat and drink, which will help him to
fast more.  

I say: There is no reason
why it should not be interpreted in a manner that is more general than what
has been mentioned. Everyone rejoices according to his status, because
people vary with regard to that. Some of them feel a kind of joy that is
permissible, and that is natural. Others feel a kind of joy that is
mustahabb, if it is because of the reasons mentioned above.
