What is the ruling on drinking coffee before the dawn (Fajr) adhan in Ramadan, when the drinker knows that it causes him sleeplessness and activity?

There is no harm in drinking coffee or other beverages during the nights of Ramadan before dawn, based on the Almighty's saying: "And eat and drink until the white thread of dawn becomes distinct to you from the black thread [of night]." And the fact that it invigorates or leads to staying up late does not affect its permissibility. Rather, this should be utilized by waking up for suhoor and increasing acts of seeking forgiveness, supplication, and obedience.
