It was Hazrat Thanvi’s routine practice, that whenever he wrote a letter making a recommendation for someone, he always added this statement, “If the favour being asked is not against your rules and other considerations, then kindly do it for this person”. 

Sometimes he also added these words, “If what is being asked is against your other considerations, and you chose not to do it, I won’t be the least bit upset.” The reason for adding these words, was to give the person full freedom, in making their decision, without any undue pressure, and also for making sure that they won’t feel bad, if they did not consider it prudent to act on the recommendation. This is the correct way of doing Sifarish or making a recommendation.
