What is the ruling on a man singing for women, accompanied only by a tambourine (daff) via a special CD recording for weddings, and selling it in stores, due to the high prices of women who sing at weddings?

We have previously clarified the ruling on a woman listening to a man's singing and anashid, stating that it is permissible provided it is free from musical instruments, with the exception of the daff (tambourine), which the preponderant opinion permits for men. Accordingly, if the recorded material is free from musical instruments and other forbidden elements, and temptation is safeguarded against, there is no objection to purchasing and listening to it, especially during wedding celebrations and holidays.
