"I am as my slave expects me to be" means that one should have the conviction that He accepts repentance, grants pardon, relieves people of their tensions and emancipates them from their troubles. Along with this conviction one should do good deeds which please Allah and avoid such deeds which have been prohibited by Him. With this conduct, one should hope for the best from Allah. This approach is similar to that of a cultivator who ploughs his land, sows the seed, waters it, takes every possible care of it and then cherishes hope for a good crop. It can also be linked to the endeavours of a person who intends to become a scholar, or a physician or an engineer. The first and foremost requirement to pursue his ambition is to study the books through which he can gain the required knowledge. For every work one intends to do, one has to first make a foundation and then acquire the means essential for it. It is only then that one can hope to achieve one's aim.
Similar is the case of associating good hopes with Allah. Unless a person does not furnish the foundation of Faith and good deeds for it, it will be unwise to associate good hopes with Allah. A slave who rather than serving his master runs away or annoys him and still hopes that his master being so kind will not take him to task for his excesses would be called stupid by the people. The same is true of Allah, who is certainly the Most Compassionate, the Most Merciful and Forgiving. But for whom is He so? The answer is for His faithful and obedient slaves and not for those who are followers of Satan. For Satan and his followers, Allah's Decision is that: "I will fill Hell with you (Iblis) and those of them (mankind) that follow you, together." (38:85).
