If one has a crumpled check, it nevertheless can still be cashed. This is because the date on the check is still valid. This is in contrast to a fancy check that even if it is written for a large sum of money can’t be cashed if it is passed the expiration date. The same applies to Tefila that even if one has an amazing Tefila, it needs to be within the Zeman. An inferior Tefila within the Zeman is much greater. When the Imrei Emes (1865-1948) became the Gerrer Rebbe, he changed the custom to now davening with Zeman Tefila.
When he was challenged- how could he change what his father did, he retorted, that back then they would get up early, recite Tehillim and prepare for a powerful Tefila. This was similar to the חסידים הראשונים who would prepare for an hour before davening. So it is understandable to daven late. However, nowadays many arise late and then daven. The Imrei Emes then gave the metaphor of one who comes home and is waiting for dinner. Although it is 7 in the evening, it is still not ready. 7:30 comes and the food still isn’t ready. The same is at 8 p.m. The husband thinks to himself if is not ready yet, she must be preparing a lavish feast. Then at 9:00, his wife comes and gives him a tuna sandwich for dinner. What a disappointment! The same applies with Tefila. In the earlier generations, although they davened late, it was easy for Hashem to overlook that, since they made it worthwhile with their preparations prior to davening. But nowadays where many get up late and don’t daven like earlier generations, to offer a Tefila after the Zeman is improper.
