Keeping the trousers below the ankles while playing sports

Salaam, 

I am aware that it is necessary for a Muslim male to keep his trousers above his ankles at all times. However, sometimes while I’m playing a sport such as basketball or soccer, my trousers fall below my ankles. If I fix it right away I will fall behind in the game by losing the ball or letting my opponent pass by me to the goal. Is it okay if I wait till the play stops to pick up my trousers? Or will I be sinful if I leave them for that short period of time?

 بسم الله الرحمن الرحيم

الجواب حامدا ومصليا ومسلما

As you have stated, it is necessary for men to keep their trousers above their ankles. This is mentioned in many ahadith. Consider the following:

 The Prophet (may Allah bless him and give him peace) has mentioned “The believer’s (length of) cloth should be to his mid shin, and there is no sin if it hangs between that and the ankles. And that which goes beneath the ankles is worthy of the fire” (Ahmad)

There are many ahadith similar to the one mentioned above that men should not let their trousers fall below their ankles.

If the trousers do happen to fall below the ankles after trying to keep them above, for example, while playing sports, insha Allah there will be no sin.
