6042 – What is Really Most Important? -

A. Indeed there are many. A common example for your particular situation would be that while learning Torah is one of the most important mitzvot, if it comes into conflict with a mitzvah that only you can do, the mitzvah takes precedence. (Moed Katan 9b, Rambam - Talmud Torah 3:4) If you can get someone else to do the mitzvah, then you can continue learning Torah. One explanation for this halacha is that a person's learning should lead up to fulfilling the mitzvot and if a person abandons fulfilling mitzvot in order to learn Torah, it indicates that one's learning isn't done in order to fulfill the mitzvot. (Rabbenu Yonah (Brachot 9b.)

Another explanation for this is that learning Torah is all encompassing and really one should learn all of the time. If one wouldn't interrupt learning in order to do other mitzvot, one would never get a chance to do any mitzvot which Hashem commanded. (ibid)
