"You may build large houses, hire many servants, have at your disposal large limousines, but, with all those luxuries, when you lie down on your bed at night, sleep eludes you although the bed on which you lie is the best available, the mattress the most superior and the pillows most ideal. You keep awake all night, now turning to the right, now to the left. You have to take sleeping pills to induce sleep but the pills lose their power after some time. We see here that all the means of comfort are available but none of these can help get the most wanted, yet elusive, sleep. These means are ineffective in removing restlessness. Only Allah can help remove it. On the other side of the world there is the labourer who has neither a worthy bed to sleep on nor a proper room yet when he goes to sleep he wakes up after eight hours of sound sleep. Now, decide for yourself who is comfortable, the labourer or the rich man? Remember, only Allah grants comfort. The means to comfort cannot provide it. Contentment and comfort are not something that may be bought although the means of comfort may be bought at will."
