How Much Darood to Send

Ubai bin Ka’ab (may Allah be pleased with him), who said:

‘I said, ‘O Messenger of Allah, I supplicate often, so how much of my supplication should I devote to you?’

He replied, ‘as you desire’.

I said, ‘a quarter of it?’

He said ‘as you desire, but if you were to increase upon this, it would be better for you.’

I said, ‘half of it?’ He said, ‘as you desire, but if you were to increase upon this, it would be better for you.’

I said, ‘two-thirds of it?’

He said again, ‘as you desire, but if you were to increase upon this, it would be better for you.’
Finally I said, ‘and if I dedicate my supplication in its entirety to you?’ He said, ‘then your needs will be satisfied, and your sins forgiven.’
