Peace, one and all...
I was making wudu this evening for my Isha prayer and my wife called me, as she needed something from me. Often, in the past, I would have called back (possibly being angered by the interruption). Tonight, by contrast, it occured to me that I should keep silent whilst making wudu.
Al hamdu lillah, it made a real difference. Not only was I able to concentrate better on my wudu, it also meant that I didn't repsond without thinking.
There is, indeed, value in silence.
