Is the failure to perform supererogatory acts of worship—such as fasting on the Day of 'Arafah and 'Ashura'—considered a sign of Allah's displeasure with His servant, especially when there are circumstances preventing their performance?

The sign of goodness is for a servant to love obedience and desire to draw closer to Allah. He must exert his utmost effort in this, for the sweetness of worship comes only after enduring hardships and striving. Allah's pleasure is attained by performing obligations and abandoning prohibitions. As for supererogatory acts, they are recommended for the perfection of reward. The inability to perform supererogatory acts sometimes due to an excuse is not a sign of displeasure. If a servant habitually performs an act of worship and is then prevented from it by an impediment (such as illness or travel), Allah records its reward for him out of His grace, as the Prophet, peace and blessings be upon him, said: "If a servant falls ill or travels, Allah records for him what he used to do when he was healthy and resident." An excuse preventing worship, such as menstruation, does not mean that Allah does not love the servant; rather, one must submit to Allah's decree and know that one is rewarded for one's good intention, and Allah does not let the reward of those who do good deeds be lost. And whoever intends good, Allah records the reward for him based on his intention, as in the Prophet's saying, peace and blessings be upon him: "This world is for four types of people..." where he equated the reward of one who was not granted wealth and knowledge but intended to act as if he were granted knowledge and wealth and acted upon them, provided the intention was sincere.
