What is the ruling on saying "May I be your ransom" (fadaytuk), "We sacrifice ourselves for you" (nafdak), or "May he be ransomed for you" (fadak), and saying "May my heart be at your service" (ya labba qalbik), "At your service" (labeeh), or "At your service, so-and-so" (labbaik ya fulan), and saying "It's too early" (badri), to which the other replies "From your lifespan" (min umrik), and saying "O dearest to my heart" (ya bad qalbi), "O dearest in the world" (ya bad al-dunya), or "O dearest of my kin" (ya bad hayyi)?

It is permissible to say "Fadaytuk" (I sacrifice myself for you), "Nafdak" (We sacrifice ourselves for you), or "Fadak" (May I be sacrificed for you), based on the Sunnah. Similarly, it is permissible to say "Labbaik ya Fulan" (Here I am, O so-and-so) or "Labbaih." As for the phrase "Badri min omrik" (May my life be taken before yours), it is intended as a prayer for long life, and it is permissible, though it is better to qualify it with obedience (to Allah). The phrase "Ya ba'd hayyi" (O the dearest part of my life) is meant to express affection, and it may have been derived from the saying of Suffanah bint Hatim al-Ta'i.
