Is it permissible to supplicate to Allah by means of His attributes mentioned in the hadiths, such as laughter and hurrying (harwala)?

Supplicating through the beautiful names and attributes of Allah is legitimate and established in the Sunnah (definition), such as supplicating through the attribute of laughter, which has been affirmed for Allah Almighty, believing in it without kayf (modality) or tamthil (likening). As for supplicating through "hurwala" (trotting/hastening) mentioned in the Hadith (definition) Qudsi, there is no harm in it, as hurwala here means Allah's swift reward to His servant, and it is not a literal physical movement. Similarly, the servant's drawing near through obedience is met with Allah's drawing near through reward.
