Is the sadness and pain that the questioner feels after her father's death contrary to the reality of patience and contentment, and is her supplication for her father, "O Allah, You are Peace, and from You is Peace; blessed and exalted are You, O Possessor of Majesty and Honor, I ask You to grant my father peace in his grave and to grant him peace on the Day he is resurrected alive," correct?

No one is free from the calamities of this world. The believer must be patient, and the rank of contentment (rida) is superior and carries a greater reward. Intense sadness, which is an involuntary feeling, does not negate patience as long as it remains an internal feeling. What is required is that the Muslim not respond to sorrows or dwell on them so that they do not affect his life and acts of worship, and that he occupy himself with what is beneficial, for sadness is stirred by Satan to incapacitate the Muslim. Contentment can be achieved by thinking that the calamity is a written decree, for sadness will not remove it, and by reflecting on the reward of contentment, "Whoever is content, for him is contentment." The father's supplication is good, and we ask Allah to answer it and to compensate him with what is better.
