There are marks like these...
There are marks like these, and even more hidden than that, which show no such indications: This means that he may perform a [righteous] deed sincerely without desiring anyone to notice it, nor does he like it to show, yet he expects people to start greeting him, to be generous to him, to meet him with a smile, with respect, to praise him, to be energetic in carrying out his errands, to be tolerant as they trade with him, etc. If he goes -to a meeting place, they make room for him.
If anyone falls short of doing any of these things, he will find it in his heart to be too heavy, and he will find it unsuitable for his status. It is as if he is rewarded by people for the worship which he hides, so much so that had he not 'performed such worship, he would not have demanded all of this, nor would he have found it unacceptable when people treat him any less than that. In my view, this has roots which also extend to conceit.
In reality, he demands that from Allah, the most Glorified One, and even wonders why the Almighty did not cast love for him in the hearts of people so they may respect him although he did perform that "sincere" act of worship!
As a whole, unless the presence of worship is similar to its absence with regard to everything relevant to people, and had one not contended himself with the fact that Allah knows about what he does, such an individual will not be free of pretension, even as low as the sound of ants' tracks, nor is he free of conceit either which we, by the will of Allah, will discuss. It is possible this much pretension voids one's rewards.
Nobody is spared such type of pretension except Allah's sincere worshippers, for Satan can have no way of reaching them. Perhaps a reference to this lies in a statement by the Commander of the Faithful Ali (a.s) who is quoted as having said. "Allah, the most Great, the most Exalted, will say to those who recite [the Holy Qur'an in public] on the Judgment Day: 'Did people not sell to you cheap? Did people not start greeting you'?
