Rolling up the Sleeves while performing Salaah

Q: Salaah-406: There is a man who is in the habit of rolling up his sleeves in salaah when it is hot. Will this create a deficiency in his salaah?

Answer: Rolling up the sleeves of both arms in salaah is an excessive act (Amal Katheer), which will nullify the salaah. Shaami (Vol.1 Pg"599) states that while it is Makrooh to start the salaah with the sleeves rolled up, rolling up the sleeves in salaah is an excessive act (Amal Katheer), which will nultify the salaah.

If a person's sleeves were rolled up to make wudhu and in eagerness to join the Jamaa'ah he starts salaah with the sleeves still rolled up, he should slowly roll them back down a little at a time while performing salaah. He must however not do an excessive act to get them down such as using both hands to do so because if he does commit an excessive act, his salaah will be nullified. Perform salaah with sleeves rolled up to the elbows and with fashionable clothing such as short-sleeved shirts will render the salaah Makrooh. And Allaah knows best what is most correct.
