Clubbing Provision

I am told that a gift received from the mother-in-law by the daughter-in-law will be subject to clubbing provisions in respect of income derived from such sums gifted. Is this true? I would be grateful for an early response.Many thanks in advance. {On the contrary it seems that a gift received by the son-in-law from the mother-in-law will not attract the clubbing provisions for the income derived from such gift! Why this anamoly? I'm confused.Please help.}
