My friend took the not-so-subtle hint and kindly translated this post. THANK YOU AND MAY HASHEM FULFILL YOUR EVERY HEARTS DESIRE LI'TOVA!
The custom among chassidim was to daven later. The holy author of the Bnei Yissachar [Rabbi Tzvi Elimelech Spira, zt"l (1783-1841),] endorsed this practice of not being strict about zman tefilla, explaining that the reason for this is that, regrettably, we are very מגושמים, and when one arises from slumber he is still completely מגושם ; his mind isn't there yet, and who knows how his sleep affected him.
A Jew should rise and say modeh ani and cry to Hashem in bircas hatorah and immediately take a Gemara and start to learn, and learn for several hours before tefilla; at least a page or two of Gemara and Tosfos. He delves into toras emes, and separates himself a bit from physicality and purifies his thoughts, and after this, he can stand and daven to Hashem. His tefilla is of a different character than that of one who wakes up in the morning and heads to davening straight from his bed, because it's not possible to daven like that. Even if he runs to the mikvah and tovels, if he spends his time on nonsense and foolish words, then it is not, as he imagines, that he is cleansing himself; rather, he is making himself tamei there.
One who wants to daven as a Jew needs to learn Gemara and Tosfos first, before davening; and one who does so will surely be blessed. Regarding one who wants to daven early, with sunrise - he should awaken in the middle of the night, and learn Gemara and Tosfos for a few hours, and then he can daven at sunrise.[לא כל הרוצה ליטול את השם יבוא ויטולAnd not anyone who wishes ליטול את השם can just come and do so,] because to daven just by muttering words, while his head is elsewhere, is no mitzva.
See the gemara that says that one who is unable to concentrate should not daven, and such a tefilla is like a korban about which it is said, "זבח רשעים תועבה" the korban of a rasha is an abomination.
